(NON-)KOSZULITY OF OPERADS FOR n-ARY ALGEBRAS, COHOMOLOGY AND DEFORMATIONS
نویسنده
چکیده
We investigate Koszulity of operads for various n-ary algebras. We then focus to algebras with one anti-associative operation. Since the corresponding operad is not Koszul, the deformation cohomology differs from the standard one. We describe the relevant part of the deformation cohomology for this type of algebras using the minimal model for the antiassociative operad. In the remaining sections we discuss free partially associative algebras and formulate open problems.

The Cohomology of Algebras over Moduli Spaces
The purpose of this paper is to introduce the cohomology of various algebras over an operad of moduli spaces including the cohomology of conformal field theories (CFT’s) and vertex operator algebras (VOA’s). This cohomology theory produces a number of invariants of CFT’s and VOA’s, one of which is the space of their infinitesimal deformations. The paper is inspired by the ideas of Drinfeld [5],...
متن کاملIntrinsic Brackets and the L∞-deformation Theory of Bialgebras
We show that there exists a Lie a bracket on the cohomology of any type of (bi)algebras over an operad or a prop, induced by an L∞-structure on the defining cochain complex, such that the associated L∞-master equation captures deformations. This in particular implies the existence of a Lie bracket on the Gerstenhaber-Schack cohomology [7] of a bialgebra that extends the classical intrinsic brac...
متن کاملLie-admissible Algebras and Operads
A Lie-admissible algebra gives a Lie algebra by anticommutativity. In this work we describe remarkable types of Lie-admissible algebras such as Vinberg algebras, pre-Lie algebras or Lie algebras. We compute the corresponding binary quadratic operads and study their duality. Considering Lie algebras as Lie-admissible algebras, we can define for each Lie algebra a cohomology with values in an Lie...

I work on the cohomology, structure, and representations of various types of rings, such as Hopf algebras and group-graded algebras. My research program involves collaborations with many mathematicians, including work with postdocs and graduate students. Below is a summary of some of my past and ongoing research projects, which fall loosely into three categories: Hochschild cohomology and defor...
