We thus have the graded category of graded groups; we generally suppress many degree suffixes by working in this category. Tensor products Given two graded groups Aand B, their tensor product A⊗ B is the graded group with components (A⊗B) n = L i+j=n A i⊗ B j. Thus (A⊗B) n is generated by elements a⊗b, where a∈ A, b∈ B, and ...

WebSep 1, 2024 · The graded Poisson algebra C, that we call Keller-Waldmann Poisson algebra, is a complex that controls deformation. Keller-Waldmann algebra elements are n-ary brackets and each bracket comes with a symbol. In degree 3, the symbol is the anchor of the Courant structure. WebGiven a differential graded Lie algebra (dgla) L satisfying certain conditions, we construct Poisson structures on the gauge orbits of its set of Maurer-Cartan (MC) elements, termed Maurer-Cartan-Poisson (MCP) structures. They associate a compatible Batalin-Vilkovisky algebra to each MC element of L. An MCP structure is shown to exist for a ...
Webas a graded Lie algebra under the Gerstenhaber bracket. Each deformation of the algebra arises from a (noncommutative) Poisson structure, that is, an element of Hochschild cohomology in degree 2 whose Gerstenhaber square bracket is zero. Thus, a rst step in understanding an algebra’s deformation theory is a depiction of the Gerstenhaber bracket.
