We regard the classification of rational homotopy types as a problem in algebraic deformation theory: any space with given cohomology is a perturbation, or deformation, of the "formal" space with that cohomology. The classifying space is then a "moduli" space --- a certain quotient of an algebraic variety of perturbations. The description we give of this moduli space links it with corresponding structures in homotopy theory, especially the classification of fibres spaces with fixed fibre F in… 

Infinity structures and higher products in rational homotopy theory

Rational homotopy theory classically studies the torsion free phenomena in the homotopy category of topological spaces and continuous maps. Its success is mainly due to the existence of relatively

A moduli space for rational homotopy types with the same homotopy lie algebra

Since Quillen proved his famous equivalences of homotopy categories in 1969, much work has been done towards classifying the rational homotopy types of simply connected topological places. The

Rational homotopy theory of automorphisms of manifolds

We study the rational homotopy types of classifying spaces of automorphism groups of smooth simply connected manifolds of dimension at least five. We give dg Lie algebra models for the homotopy

Rational Homotopy Theory and Deformation Problems from Algebraic Geometry

This paper is a description of research I have been doing over the last four years, applying some of the methods and ideas of rational homotopy theory as developed by Chen, Quillen and Sullivan, to

Operads and Maurer–Cartan spaces

This thesis is inscribed in the topics of operad theory and homotopical algebra. Suppose we are given a type of algebras, a type of coalgebras, and a relationship between those types of algebraic

Homotopy theory of complete Lie algebras and Lie models of simplicial sets

In a previous work, by extending the classical Quillen construction to the non‐simply connected case, we have built a pair of adjoint functors, model and realization, between the categories of

Higher Lie theory

We present a novel approach to the problem of integrating homotopy Lie algebras by representing the Maurer-Cartan space functor with a universal cosimplicial object. This recovers Getzler's original

Operads and Moduli Spaces

This thesis is concerned with the application of operadic methods, particularly modular operads, to questions arising in the study of moduli spaces of surfaces as well as applications to the study of

THE CLASSIFYING SPACE FOR FIBRATIONS AND RATIONAL HOMOTOPY THEORY

Over 50 years ago, Jim Stasheff [33] solved the classification problem for fibrations with fibre a finite CW complex X. He constructed a universal X-fibration of the form: X → UE → Baut(X) with base

Koszul duality and homotopy theory of curved Lie algebras

This paper introduces the category of marked curved Lie algebras with curved morphisms, equipping it with a closed model category structure. This model structure is---when working over an

The $A(\inft)$-algebra structure in homology of a DG-algebra is constructed. This structure is unique up to isomorphism of $A(\infty)$ algebras. Connection of this structure with Massey products is
