We look at a measure, linfinity , on the infinite-dimensional space, Rinfinity , for which we attempt to put forth an analogue of the Lebesgue density theorem. Although this measure allows us to find partial results, for example for continuous functions, we prove that it is impossible to give an analogous theorem in full generality. In particular, we proved that the Lebesgue density of probability density functions on Rinfinity is zero almost everywhere.

Let X be an affine algebraic variety with a transitive action of the algebraic automorphism group. Suppose that X is equipped with several fixed point free non-degenerate SL_2-actions satisfying some mild additional assumption. Then we prove that the Lie algebra generated by completely integrable algebraic vector fields on X coincides with the set of all algebraic vector fields. In particular, we show that apart from a few exceptions this fact is true for any homogeneous space of form G/R where G is a linear algebraic group and R is a proper reductive subgroup of G.

Cette thèse est consacrée à l'étude des équations de Mahler et des solutions de ces équations, appelées fonctions de Mahler. Des exemples classiques de fonctions de Mahler sont les séries génératrices des suites automatiques. La première partie de cette thèse porte sur les aspects galoisiens des équations de Mahler. Notre résultat principal est un analogue pour ces équations du théorème de densité de Schlesinger selon lequel la monodromie d'une équation différentielle à points singuliers réguliers est Zariski-dense dans son groupe de Galois différentiel. Pour cela, nous commençons par attacher une paire de matrices de connexion à chaque équation de Mahler singulière régulière. Ces matrices nous permettent de construire un sous-groupe du groupe de Galois de l'équation de Mahler et nous montrons que ce sous-groupe est Zariski-dense dans le groupe de Galois. La seule hypothèse de ce théorème de densité est le caractère singulier régulier de l'équation de Mahler considérée. La deuxième partie de cette thèse est consacrée à la construction d'un algorithme qui permet de reconnaître si une équation de Mahler est singulière régulière
This thesis is devoted to the study of Mahler equations and the solutions of these equations, called Mahler functions. Classic examples of Mahler functions are the generating series of automatic sequences. The first part of this thesis deals with the Galoisian aspects of Mahler equations. Our main result is an analog for Mahler equations of the Schlesinger’s density theorem according to which the monodromy of a regular singular differential equation is Zariski-dense in its differential Galois group. To this end, we start by attaching a pair of connection matrices to each regular singular Mahler equation. These matrices enable us to construct a subgroup of the Galois group of the Mahler equation and we prove that this subgroup is Zariski-dense in the Galois group. The only assumption of this density theorem is the regular singular condition on the considered Mahler equation. The second part of this thesis is devoted to the construction of an algorithm which recognizes whether or not a Mahler equation is regular singular

Nós consideramos o seguinte problema. Fixado um grafo H e um número real \\alpha \\in (0,1], determine o menor \\beta = \\beta(\\alpha, H) que satisfaz a seguinte propriedade: se G é um grafo de ordem n no qual cada subconjunto de [\\alpha n] vértices induz mais que \\beta n^2 arestas então G contém H como subgrafo. Este problema foi iniciado e motivado por Erdös ao conjecturar que todo grafo livre de triângulo de ordem n contém um subconjunto de [n/2] vértices que induz no máximo n^2 /50 arestas. Nosso resultado principal mostra que i) todo grafo de ordem n livre de triângulos e pentágonos contém um subconjunto de [n/2] vértices que induz no máximo n^2 /64 arestas, e ii) se G é um grafo regular de ordem n livre de triângulo, com grau excedendo n/3, então G contém um subconjunto de [n/2] vértices que induz no máximo n^2 /50 arestas. Se além disso G não é 3-cromático então G contém um subconjunto de [n/2] vértices que induz menos de n^2 /54 arestas. Como subproduto e confirmando uma conjectura de Erdös assintoticamente, temos que todo grafo regular de ordem n livre de triângulo com grau excedendo n/3 pode ser tornado bipartido pela omissão de no máximo (1/25 + o(1))n^2 arestas. Nós também fornecemos um contraexemplo a uma conjectura de Erdös, Faudree, Rousseau e Schelp.
We consider the following problem. Fixed a graph H and a real number \\alpha \\in (0,1], determine the smallest \\beta = \\beta(\\alpha, H) satisfying the following property: if G is a graph of order n such that every subset of [\\alpha n] vertices spans more that \\beta n^2 edges then G contains H as a subgraph. This problem was initiated and motivated by Erdös who conjectured that every triangle-free graph of order n contains a subset of [n/2] vertices that spans at most n^2 /50 edges. Our main result shows that i) every triangle- and pentagon-free graph of order n contains a subset of [n/2] vertices inducing at most n^2 /64 edges and, ii) if G is a triangle-free regular graph of order n with degree exceeding n/3 then G contains a subset of [n/2] vertices inducing at most n^2 /50 edges. Furthermore, if G is not 3-chromatic then G contains a subset of [n/2] vertices inducing less than n^2 /54 edges. As a by-product and confirming a conjecture of Erdös asymptotically, we obtain that every n-vertex triangle-free regular graph with degree exceeding n/3 can be made bipartite by removing at most (1/25 + o(1))n^2 edges. We also provide a counterexample to a conjecture of Erdös, Faudree, Rousseau and Schelp.

We consider a simple one-dimensional random dynamical system with two driving vector fields and random switchings between them. We show that this system satisfies a one force - one solution principle and compute its unique invariant density explicitly. We study the limiting behavior of the invariant density as the switching rate approaches zero and infinity and derive analogues of classical probabilistic results such as the central limit theorem and large deviations principle.

The present paper reports on recent efforts of utilizing symbolic computing for identifying failure criteria cross reducibility from the perspective of theorem proving. Utilizing equational theorem proving algorithms and Gro¨bner Basis polynomial theorem provers implemented in Mathematica we have proven a number of interesting theorems related to the area of structural failure criteria for anisotropic and particularly orthotropic materials. The main contribution of this work is the demonstration of the tremendous utility of symbolic algebra for engineering applications as well as the demonstration of the idea that all failure criteria presented in the literature up to know can be proven under certain conditions to be special forms of general criteria relating to the strain energy density function associated with material continua. Two specific examples are presented and discussed along with a theorem proving the existence of a dual form of all stress space based criteria to equivalent one expressed in strain space.

Higher order effects in ferroelectric materials are investigated by integrating electron density calculations using quantum mechanics into a homogenized, nonlinear continuum modeling framework. Electrostatic stresses based on the Hellmann-Feynman theorem are used to identify connections with the higher order quadrupole density. These higher order relations are integrated into a nonlinear mechanics free energy function to simulate electromechanical coupling. A specific example is investigated by conducting density functional theory (DFT) calculations on barium titanate and fitting the results to a thermodynamic potential function. Through the use of nonlinear geometric effects, electromechanical coupling is obtained without the use of electrostrictive or piezoelectric coupling coefficients.

Анотація:

A theory of the vibrational spectra of glasses, based on allowance for the statistical fluctuations of the local elastic constants, is proposed. The existence is established of two characteristic energies h, and h, , dividing the spectrum into regions of qualitatively different behavior of the density of states n (h). At low frequencices w 4 w, the increase of the density of states is determined by the additive contributions of phonons and mutually noninteracting quasilocal vibrations in random soft atomic potentials in the glass. In the intermediate region w , 5 w 5 w, the quasilocal vibrations interact strongly with phonons, and this makes their contributions superadditive. For w > w, the growth of n (h) slows down. As a result, n (h) increases at first more rapidly and then more slowly than the Debye density of states. An analytical expression for n (h) is obtained in the T-matrix formalism in the region w <a,, including the region of strong scattering. A numerical calculation of n (h) is performed in the coherent-potential approximation. The theory predicts qualitatively universal behavior of n (h) in different glasses.
