We develop the basic theory of quasi-categories (a.k.a. weak Kan complexes or ([infinity], 1)- categories as in [BV73], [Joy], [Lur06]) from first principles, i.e. without reference to model categories or other ideas from algebraic topology. Starting from the definition of a quasi-category as a simplicial set satisfying the inner horn-filling condition, we define and prove various properties of quasi-categories which are direct generalizations of categorical analogues. In particular, we look at functor quasi-categories, Hom-spaces, isomorphisms, equivalences between quasi-categories, and limits. In doing so, we employ exclusively combinatorial methods, as well as adapting an idea of Makkai's ("very subjective morphisms," what turn out in this case to be simply trivial Kan fibrations) to get a handle on various notions of equivalence. We then begin to discuss a new approach to the theory of left (or right) fibrations, wherein the quasi-category of all left fibrations over a given base S is described simply as the large simplicial set whose n-simplices consist of all left fibrations over S x [delta]n.
(cont.) We conjecture that this large simplicial set is a quasi-category, and moreover that the case S = * gives an equivalent quasi-category to the commonly-held quasi-category of spaces; we offer some steps towards proving this. Finally, assuming the conjecture true, we apply it to give simple descriptions of limits in this quasi-category, as well as a straightforward construction of a Yoneda functor for quasi-categories which we then prove is fully faithful.

Texto completoIn this thesis we prove a Tannaka duality theorem for (infini, 1)-categories. Classical Tannaka duality is a duality between certain groups and certain monoidal categories endowed with particular structure. Higher Tannaka duality refers to a duality between certain derived group stacks and certain monoidal (infini, 1)-categories endowed with particular structure. This higher duality theorem is defined over derived rings and subsumes the classical statement. We compare the higher Tannaka duality to the classical theory and pay particular attention to higher Tannaka duality over fields. In the later case this theory has a close relationship with the theory of schematic homotopy types of Toën. We also describe three applications of our theory : perfect complexes and that of both motives and its non-commutative analogue due to Kontsevich

Texto completoIf M is a symplectic manifold then the space of smooth loops C(S^1,M) inherits of a quasi-symplectic form. We will focus in this thesis on an algebraic analogue of that result.In their article, Kapranov and Vasserot introduced and studied the formal loop space of a scheme X. It is an algebraic version of the space of smooth loops in a differentiable manifold.We generalize their construction to higher dimensional loops. To any scheme X -- not necessarily smooth -- we associate L^d(X), the space of loops of dimension d. We prove it has a structure of (derived) Tate scheme -- ie its tangent is a Tate module: it is infinite dimensional but behaves nicely enough regarding duality.We also define the bubble space B^d(X), a variation of the loop space.We prove that B^d(X) is endowed with a natural symplectic form as soon as X has one.To prove our results, we develop a theory of Tate objects in a stable infinity category C. We also prove that the non-connective K-theory of Tate(C) is the suspension of that of C, giving an infinity categorical version of a result of Saito.The last chapter is aimed at a different problem: we prove there the existence of a Lie structure on the tangent of a derived Artin stack X. Moreover, any quasi-coherent module E on X is endowed with an action of this tangent Lie algebra through the Atiyah class of E. This in particular applies to not necessarily smooth schemes X

Texto completoIt is well-known that very simple theoretic constructs such as Either (type-theoretic equivalent of the logical "or" operator), State (composable state transformers), Applicative (generalized function application), and Monad (generalized sequential program composition) structures (as they are named in Haskell) cover a huge chunk of what is usually needed to elegantly express most computational idioms used in conventional programs. However, it is conventionally argued that there are several classes of commonly used idioms that do not fit well within those structures, the most notable examples being transformations between trees (data types, which are usually argued to require ether generalized pattern matching or heavy metaprogramming infrastructure) and exception handling (which are usually argued to require special language and run-time support). This work aims to show that many of those idioms can, in fact, be expressed by reusing those well-known structures with minor (if any) modifications. In other words, the purpose of this work is to apply the KISS (Keep It Stupid Simple) and/or Occam's razor principles to algebraic structures used to solve common programming problems. Technically speaking, this work aims to show that natural generalizations of Applicative and Monad type classes of Haskell combined with the ability to make Cartesian products of them produce a very simple common framework for expressing many practically useful things, some of the instances of which are very convenient novel ways to express common programming ideas, while others are usually classified as effect systems. On that latter point, if one is to generalize the presented instances into an approach to design of effect systems in general, then the overall structure of such an approach can be thought of as being an almost syntactic framework which allows different effect systems adhering to the general structure of the "marriage" framework to be expressed on top of. (Though, this work does not go into too much into the latter, since this work is mainly motivated by examples that can be immediately applied to Haskell practice.) Note, however, that, after the fact, these technical observation are completely unsurprising: Applicative and Monad are generalizations of functional and linear program compositions respectively, so, naturally, Cartesian products of these two structures ought to cover a lot of what programs usually do

Abstract In this thesis, we study a class of so-called cohomologically proper stacks from various perspectives, mainly concentrating on the p-adic context. Cohomological properness is a relaxed properness condition on a stack which roughly asks the cohomology of any coherent sheaf to be finitely generated over the base. We extend some of the techniques available for smooth proper schemes to smooth cohomologically proper stacks, featuring in particular recently developed theory of prismatic co-homology and the classical Deligne-Illusie method for the Hodge-to-de Rham degeneration. As main applications we prove the Totaro's conjectural inequality between the dimensions of the de Rham and the singular F[subscript p]-cohomology of the classifying stack of a reductive group, compute the ring of prismatic characteristic classes at non-torsion primes and give some new examples of the Hodge-to-de Rham degeneration for stacks in characteristic 0. We also study some descent properties of certain Brauer group classes on conical resolutions, a question having some applications to the theory of Fedosov quantizations in characteristic p. Some surprising results about the G[subscript m]-weights of differential 1-forms that are obtained along the way, originally motivated the attempt to generalize the integral p-adic Hodge theory to the setting of cohomologically proper stacks.

Texto completoThe study of fibre bundles is an important subject in complex geometry. This thesis considers the particular case of affine line bundles over complex spaces. Affine line bundles are a natural generalisation of line bundles. The first part of this thesis studies the classical moduli problem and the existence of fine moduli spaces. In analogy to the study of line bundles, an affine Picard functor is defined. It is shown that this moduli space will (unless trivial) not be Hausdorff which leads to the study of framed affine line bundles. An exact criterion for the existence of a moduli space for this problem is given. Since the existence of such moduli spaces is very rare, the modern approach of stacks is used in the second part. To give a simpler description of this stack, the theory of fibrewise split extensions is developed. This theory is very general and is of independent interest. For a complex projective variety X, this approach allows to identify the stack of affine line bundles with a quotient stack of linear fibre spaces over the Picard scheme Pic(X). As an application, the homotopy type of this stack is calculated
