Abstract:

Abstract Since its discovery by Hitchin in 1987, G-Hitchin systems for a reductive complex Lie group G have extensively been studied. For example, the generic fibers are nowadays well-understood. In this paper, we show that the smooth parts of G-Hitchin systems for a simple adjoint complex Lie group G are isomorphic to non-compact Calabi–Yau integrable systems extending results by Diaconescu–Donagi–Pantev. Moreover, we explain how Langlands duality for Hitchin systems is related to Poincaré–Verdier duality of the corresponding families of quasi-projective Calabi–Yau threefolds. Even though the statement is holomorphic-symplectic, our proof is Hodge-theoretic. It is based on polarizable variations of Hodge structures that admit so-called abstract Seiberg–Witten differentials. These ensure that the associated Jacobian fibration is an algebraic integrable system.

Abstract:

In this paper we continue our studies of Hitchin systems on singular curves (started in [1]). We consider a rather general class of curves which can be obtained from the projective line by gluing two subschemes together (i.e. their affine part is: Spec {f ∈ ℂ[z] : f(A(∊)) = f(B(∊)); ∊N = 0}, where A(∊), B(∊) are arbitrary polynomials). The most simple examples are the generalized cusp curves which are projectivizations of Spec {f ∈ ℂ[z] : f′(0) = f″(0) = ⋯ fN-1(0) = 0}. We describe the geometry of such curves; in particular we calculate their genus (for some curves the calculation appears to be related with the iteration of polynomials A(∊), B(∊) defining the subschemes). We obtain the explicit description of moduli space of vector bundles, the dualizing sheaf, Higgs field and other ingredients of the Hitchin integrable systems; these results may deserve the independent interest. We prove the integrability of Hitchin systems on such curves. To do this we develop r-matrix formalism for the functions on the truncated loop group GLn(ℂ[z]), zN = 0. We also show how to obtain the Hitchin integrable systems on such curves as hamiltonian reduction from the more simple system on some finite-dimensional space.

Abstract:

We study the Hitchin component in the space of representations of the fundamental group of a Riemann surface into a split real Lie group in the rank 2 case. We prove that such representations are described by a conformal structure and class of Higgs bundle we call cyclic and we show cyclic Higgs bundles correspond to a form of the affine Toda equations. We also relate various real forms of the Toda equations to minimal surfaces in quadrics of arbitrary signature. In the case of the Hitchin component for PSL(3,R) we provide a new proof of the relation to convex RP²-structures and hyperbolic affine spheres. For PSp(4,R) we prove such representations are the monodromy for a special class of projective structure on the unit tangent bundle of the surface. We prove these are isomorphic to the convex-foliated projective structures of Guichard and Wienhard. We elucidate the geometry of generic 2-plane distributions in 5 dimensions, work which traces back to Cartan. Nurowski showed that there is an associated signature (2,3) conformal structure. We clarify this as a relationship between a parabolic geometry associated to the split real form of G₂ and a conformal geometry with holonomy in G₂. Moreover in terms of the conformal geometry we prove this distribution is the bundle of maximal isotropics corresponding to the annihilator of a spinor satisfying the twistor-spinor equation. The moduli space of deformations of a compact coassociative submanifold L in a G₂ manifold is shown to have a natural local embedding as a submanifold of H2(L,R). We consider G2-manifolds with a T^4-action of isomorphisms such that the orbits are coassociative tori and prove a local equivalence to minimal 3-manifolds in R^{3,3} = H²(T⁴,R) with positive induced metric. By studying minimal surfaces in quadrics we show how to construct minimal 3-manifold cones in R^{3,3} and hence G₂-metrics from equations that are a set of affine Toda equations. The relation to semi-flat special Lagrangian fibrations and the Monge-Ampere equation is explained.

Abstract:

Soit X une courbe projective lisse et irréductible munie d'une involution σ. Dans cette thèse, nous étudions les fibrés vectoriels invariants and anti-invariants sur X sous l'action induite par σ. On introduit la notion de modules σ-quadratiques et on l'utilise, avec GIT, pour construire ces espaces de modules, puis on en étudie certaines propriétés. Ces espaces de modules correspondent aux espaces de modules de G-torseurs parahoriques sur la courbe X/σ , pour certains schémas en groupes parahoriques G de type Bruhat-Tits, qui sont twistés dans le cas des anti-invariants. Nous développons les systèmes de Hitchin sur ces espaces de modules et on les utilise pour dériver une classification de leurs composantes connexes en les dominant par des variétés de Prym. On étudie aussi le fibré déterminant sur les espaces de modules des fibrés vectoriels anti-invariants. Dans certains cas, ce fibré en droites admet certaines racines carrées appelées fibrés Pfaffiens. On montre que les espaces des sections globales des puissances de ces fibrés en droites (les espaces des fonctions thêta généralisées) peuvent être canoniquement identifier avec les blocs conformes associés aux algèbres de Kac-Moody affines twistées de type A(2)
Let X be a smooth irreducible projective curve with an involution σ. In this dissertation, we studythe moduli spaces of invariant and anti-invariant vector bundles over X under the induced action of σ. We introduce the notion of σ-quadratic modules and use it, with GIT, to construct these moduli spaces, and than we study some of their main properties. It turn out that these moduli spaces correspond to moduli spaces of parahoric G-torsors on the quotient curve X/σ, for some parahoric Bruhat-Tits group schemes G, which are twisted in the anti-invariant case.We study the Hitchin system over these moduli spaces and use it to derive a classification of theirconnected components using dominant maps from Prym varieties. We also study the determinant of cohomology line bundle on the moduli spaces of anti-invariant vector bundles. In some cases this line bundle admits some square roots called Pfaffian of cohomology line bundles. We prove that the spaces of global sections of the powers of these line bundles (spaces of generalized theta functions) can be canonically identified with the conformal blocks for some twisted affine Kac-Moody Lie algebras of type A(2)

Abstract:

This thesis is concerned with the study of the geometry and derived categories associated to the moduli problems of local systems and Higgs bundles in positive characteristic. As a cornerstone of our investigation, we establish a local system analogue of the BNR correspondence for Higgs bundles. This result (Proposition 4.3.1) relates flat connections to certain modules of an Azumaya algebra on the family of spectral curves. We prove properness over the semistable locus of the Hitchin map for local systems introduced by Laszlo–Pauly (Theorem 4.4.1). Moreover, we show that with respect to this Hitchin map, the moduli stack of local systems is étale locally equivalent to the moduli stack of Higgs bundles (Theorem 4.6.3) (with or without stability conditions). Subsequently, we study two-dimensional examples of moduli spaces of parabolic Higgs bundles and local systems (Theorem 5.2.1), given by equivariant Hilbert schemes of cotangent bundles of elliptic curves. Furthermore, the Hilbert schemes of points of these surfaces are equivalent to moduli spaces of parabolic Higgs bundles, respectively local systems (Theorem 5.3.1). The proof for local systems in positive characteristic relies on the properness results for the Hitchin fibration established earlier. The Autoduality Conjecture of Donagi–Pantev follows from Bridgeland–King–Reid’s McKay equivalence in these examples. The last chapter of this thesis is concerned with the con- struction of derived equivalences, resembling a Geometric Langlands Correspondence in positive characteristic, generalizing work of Bezrukavnikov–Braverman. Away from finitely many primes, we show that over the locus of integral spectral curves, the derived category of coherent sheaves on the stack of local systems is equivalent to a derived category of coherent D-modules on the stack of vector bundles. We conclude by establishing the Hecke eigenproperty of Arinkin’s autoduality and thereby of the Geometric Langlands equivalence in positive characteristic.

Abstract:

The purpose of this study was to investigate the use of mobile phones in organizing ad-hoc vehicle ridesharing based on hitch-hiking trips involving private car drivers and commuters in South Africa. A study was conducted to learn how hitch-hiking trips are arranged in the urban and rural areas of the Eastern Cape. This involved carrying out interviews with hitch-hikers and participating in several trips. The study results provided the design specifications for a Dynamic Ridesharing System (DRS) tailor-made to the hitch-hiking culture of this context. The design of the DRS considered the delivery of the ad-hoc ridesharing service to the anticipated mobile phones owned by people who use hitch-hiking. The implementation of the system used the available open source solutions and guidelines under the Siyakhula Living Lab project, which promotes the use of Information and Communication Technology (ICT) in marginalized communities of South Africa. The developed prototype was tested in both the simulated and live environments, then followed by usability tests to establish the viability of the system. The results from the tests indicate an initial breakthrough in the process of modernizing the ad-hoc ridesharing of hitch-hiking which is used by a section of people in the urban and rural areas of South Africa.

Abstract:

The notions of Hitchin systems and Higgs bundles (also called Higgs pairs) were introduced by N. Hitchin in 1987. They rapidly formed a subject lying on the crossroads of representation theory, symplectic geometry, and algebraic geometry. In this research area, the main objects that attract mathematicians' attention are the moduli spaces of Higgs bundles Mn,d (the moduli space of Higgs bundles is a space parameterizing the collection of all Higgs bundles). These moduli spaces have many good properties that make them interesting objects worthy of study. For example, they are symplectic manifolds, e.g. the moduli space of the Higgs bundles with rank one and degree zero is the cotangent bundle of the Jacobian variety of a Riemann surface. These moduli spaces are also equipped with Riemannian hyperkähler metrics ghk which can not be written explicitly in general, but they can be approximated by another metric, gsf which is called the semi-at metric. Roughly, we can say that ghk = gsf + correction. In fact, Gaiotto, Moore and Neitzke conjectured what the "corrections" should be in 2011[GMN13]. To find the semi-at metric of Mn,d, we first investigate the integrable system (Hitchin system) h :Mn,d → B where the map h is known as the Hitchin map. The Lagrangian fibers of the Hitchin systems are Jacobian (or Prym) varieties of spectral curves of a given compact Riemann surface. The semi-flat metric of Mn,d is induced by a special Kähler metric on B through the Lagrangian fibration. In my thesis, I will compute these metrics as explicitly as possible and give close observations to them...

Abstract:

Abstract In this paper, a unique method of deriving two kinds of models: simulation model and simplified control model for an arbitrary configuration of heavy vehicle (HV) system is proposed for the Automated Highway Systems (AHS). In the simulation model, each unit of a heavy vehicle system is considered as a free body with 6 degree of freedom unless constrained by the hitching mechanisms. The roll and pitch coupling due to constraints between connected units is investigated from the geometric point of view, and the dynamics of the hitching mechanisms are incorporated. A simplifed control model is obtained independent from the simulation model. By the proper application of Newtonian and Lagrangian mechanics to the different parts of the simplified model equations, the holonomic constraint forces are eliminated from the dynamic equations of motion. The control model is given in a closed form. As a special case, an open-loop simulation of tractor-semitrailer simulation model is presented.

Abstract:

This paper describes one example of an adjustable gooseneck trailer hitch assembly that was assigned as a senior capstone design project course at Kettering University, Flint, Michigan, USA to carry out their work from concept to testing phases of a real prototype – in short, following “Theory meets practice” concept. Typically at most other engineering colleges, students complete their capstone projects in one year, while at Kettering University, the students complete their capstone courses in one academic term that lasts only about 11 weeks. Using math and advanced Computer Aided Engineering (CAE) tools for analysis is expected. Three different groups of students enrolled in three separate courses over 3 academic terms developed two different trailer hitch devices. The first gooseneck hitch system briefly described here was the effort of a group of four students of the capstone course. They designed a manually adjustable device. However, due to time constraints, their fabricated device ended up being a rigid frame. These students carried out all the different tasks of the project more or less equitably. The second trailer hitch system described in this paper was the effort of a single student of the capstone course who designed and fabricated a compliant (adjustable) hitch system. However, due to time constraints, detailed finite element analysis (FEA) or testing of the device could not be done. A third group of two students enrolled in Applied Finite Element Analysis course in another academic term chose the compliant hitch design carried by the single student for their final class project, and attempted analysis by MatLab and FEA. Preliminary results obtained for both of these gooseneck trailer hitch systems are presented and discussed briefly in the paper. Majority of the capstone course projects carried out at Kettering University represent uniqueness in terms of completing them in one academic term.

Abstract:

Abstract This paper investigates an effectiveness of vehicle dynamic control (VDC) system based on torque vectoring technique using in-wheel-motors to improve the performance of articulated vehicle systems. A 10 degree-of-freedom (DOF) articulated vehicle model including a tractor and a single axle trailer has been developed and its responses are validated with commercial vehicle software of Trucksim. This model includes a nonlinear tire model (MF tire), a hydraulic damping at the hitch, and a traction system using in-wheel-motors at the trailer axle. In this paper, a yaw control system is developed to track the reference yaw rate with application of yaw moment at the trailer axle using torque distribution of in-wheel-motors. The effectiveness of the proposed control system is validated through simulation of sinusoidal steering maneuver on high mu and slippery road conditions. The simulation results show that in-wheel-motors can improve safety and performance of articulate vehicle systems.

Abstract:

This paper is on the design of control systems to handle the the oscillations occurring on tractors without any suspension. During transport phases, the lack of suspension causes the vehicle to bounce and pitch, and makes it difficult to control. A number of different approaches to actively damping the oscillations exist. In the current paper one of these control schemes are adopted and used together with an experimentally verified model of an agricultural tractor to determine the necessary requirements to the hitch valve by means of optimization. The design variables include controller gain, valve response time and valve dead band whereas the criteria are the comfort of the driver, the energy consumption and the loading of the mechanical parts of the hitch linkage.

Abstract:

The article presents an analysis of tests of serial and experimental upper louver sieves. The adjustments of the serial and experimental sieves were the same. Comparative tests were carried out on the harvesting of wheat of the "Bezostaya-1" variety with the reference combine "don-1500" when replacing the upper sieve. The results of tests of serial and experimental louver sieves are presented.
