Obstructions to homotopy equivalences
Abstract An obstruction theory is developed to decide when an isomorphism of rational cohomology can be realized by a rational homotopy equivalence (either between rationally nilpotent spaces, orExpand

The Lie algebra structure of tangent cohomology and deformation theory
Abstract Tangent cohomology of a commutative algebra is known to have the structure of a graded Lie algebra; we account for this by exhibiting a differential graded Lie algebra (in fact, two of them)Expand

The sh Lie Structure of Poisson Brackets in Field Theory
Abstract:A general construction of an sh Lie algebra (L∞-algebra) from a homological resolution of a Lie algebra is given. It is applied to the space of local functionals equipped with a PoissonExpand

Deformation theory and rational homotopy type
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 withExpand

Perturbation Theory in Differential Homological Algebra II
Perturbation theory is a particularly useful way to obtain relatively small differential complexes representing a given chain homotopy type. An important part of the theory is “the basic perturbationExpand

Homotopy Algebras Inspired by Classical Open-Closed String Field Theory
We define a homotopy algebra associated to classical open-closed strings. We call it an open-closed homotopy algebra (OCHA). It is inspired by Zwiebach's open-closed string field theory and also isExpand
