Cup product on $A_\infty$-cohomology and deformations

چکیده
We propose a simple method for constructing formal deformations of differential graded algebras in the category minimal $A_\infty$-algebras. The basis our approach is provided by Gerstenhaber algebra structure on $A_\infty$-cohomology, which we define terms brace operations. As an example, construct $A_\infty$-algebra from Weyl-Moyal $\ast$-product polynomial functions.

Cup-product for Leibniz Cohomology and Dual Leibniz Algebras
For any Lie algebra g there is a notion of Leibniz cohomology HL(g), which is defined like the classical Lie cohomology, but with the n-th tensor product g⊗n in place of the n-th exterior product Λ g. This Leibniz cohomology is defined on a larger class of algebras : the Leibniz algebras (cf. [L1], [L2]). A Leibniz algebra is a vector space equipped with a product satisfying a variation of the ...
متن کاملFinite Groups Acting Linearly: Hochschild Cohomology and the Cup Product
When a finite group acts linearly on a complex vector space, the natural semi-direct product of the group and the polynomial ring over the space forms a skew group algebra. This algebra plays the role of the coordinate ring of the resulting orbifold and serves as a substitute for the ring of invariant polynomials from the viewpoint of geometry and physics. Its Hochschild cohomology predicts var...
متن کاملCup product and intersection
This is a handout for my algebraic topology course. The goal is to explain a geometric interpretation of the cup product. Namely, if X is a closed oriented smooth manifold, if A and B are oriented submanifolds of X, and if A and B intersect transversely, then the Poincaré dual of A∩B is the cup product of the Poincaré duals of A and B. As an application, we prove the Lefschetz fixed point formu...
متن کاملCohomology and Deformations of Algebraic Structures
Gerstenhaber has recently initiated a theory of deformations of associative algebras [4]. The methods and results of Gerstenhaber's work are strikingly similar to those in the theory of deformations of complex analytic structures on compact manifolds. In this note we shall indicate how some of Gerstenhaber's ideas can be reformulated within a framework designed to exploit this similarity, that ...
متن کاملDolbeault Cohomology and Deformations of Nilmanifolds
In these notes I review some classes of invariant complex structures on nilmanifolds for which the Dolbeault cohomology can be computed by means of invariant forms, in the spirit of Nomizu’s theorem for de Rham cohomology. Moreover, deformations of complex structures are discussed. Small deformations remain in some cases invariant, so that, by Kodaira-Spencer theory, Dolbeault cohomology can be...
