This thesis breaks into two main parts.1) We show that there is an equivalence of categories between Lie-Rinehart algebras over a commutative algebra O and homotopy equivalence classes of negatively graded acyclic Lie infinity-algebroids. Therefore, this result makes sense of the universal Lie infinity-algebroid of every singular foliation,without any additional assumption, and for Androulidakis-Zambon singular Lie algebroids. This extends to a purely algebraic setting the construction of the universal Q-manifold of a locally real analytic singular foliation. Also, to any ideal I of O preserved by the anchor map of a Lie-Rinehart algebra A, we associate a homotopy equivalence class of negatively graded Lie infinity-algebroids over complexes computing Tor_O(A,O/I). Several explicit examples are given.2) The second part is dedicated to some applications of the results on Lie-Rinehart algebras.a. We associate to any affine variety a universal Lie infinity-algebroid of the Lie-Rinehart algebra of its vector fields. We study the effect of some common operations on affine varieties such as blow-ups, germs at a point, etc.b. We give an interpretation of the blow-up of a singular foliation F in the sense of Omar Mohsen in term of the universal Lie infinity-algebroid of F.c. We introduce the notion of longitudinal vector fields on a graded manifold over a singular foliation, and study their cohomology. We prove that the cohomology groups of the latter vanish.d. We study symmetries of singular foliations through universal Lie infinity-algebroids. More precisely, we prove that a weak symmetry action of a Lie algebra g on a singular foliation F (which is morally an action of g on the leaf space M/F) induces a unique up to homotopy Lie infinity-morphism from g to the Differential Graded Lie Algebra (DGLA) of vector fields on a universal Lie infinity-algebroid of F. We deduce from this general result several geometrical consequences. For instance, we give an example of a Lie algebra action on an affine sub-variety which cannot be extended on the ambient space. Last, we present the notion of tower of bi-submersions over a singular foliation and lift symmetries to those

Using the Koszul duality theory of operads, we make the André Quikllen cohomology of algebras over an operad explicit. This cohomologie theory is represented by a chain complex : the cotangent compex. We provide criteria for the André Quillen cohomologie theory to be an Ext-functor. In particular, this is the case for algebras over cofibrant operads and this gives a new stable homotopy property for these algebras. Then we generalize the Koszul duality theory of associative algebras in two dependant directions. On the one hand, we extend the Koszul duality theory to non necessarily augmented operads in order to treat algebras with unit. The notion of curvature appears to encode the default of augmentation. As a corollary, we obtain homotopical and cohomological theories for unital associative algebras or unital and counital Frobenius algebras. We make the case of unital associative algebras explicit. On the other hand, we generalize the Koszul duality theory to algebras over an operad. To do this, we show that the contangent complex provides the good generalization of the Koszul complex

The purpose of this thesis is to set up a general homotopy theory for categories of differential graded bialgebras. A first part is devoted to the case of bialgebras defined by a pair of operads in distribution. Classical bialgebras, Lie bialgebras and Poisson bialgebras provide examples of such bialgebra structures. The main result of this part asserts that the category of bialgebras associated to a pair of operads in distribution inherits a model category structure. The notion of a PROP provides a setting for the study of general bialgebras structures, involving operations with multiple inputs and multiple outputs as generators of the structure, in contrast to operads in distribution which only encode operations with either one single input or one single output. PROPs form a category, in which one can define a notion of cofibrant object with good homotopical properties. The second part of the thesis is devoted to the homotopy theory of bialgebras over a PROP. The main result of the thesis asserts that the categories of bialgebras associated to weakly equivalent cofibrant props have equivalent homotopy categories. We actually prove a more precise theorem asserting that this equivalence holds at the level of a simplicial localization of the categories. Our theorem implies that the category of bialgebras associated to a cofibrant resolution of a given PROP P defines a notion of bialgebra up to homotopy over P independent of the choice of the resolution, and enables us to give a sense to homotopical realization problems in this setting
