On the cyclic Formality conjecture
We conjecture an explicit formula for a cyclic analog of the Formality L∞-morphism [K]. We prove that its first Taylor component, the cyclic Hochschild-Kostant-Rosenberg map, is in fact a morphism (and a quasiisomorphism) of the complexes. To prove it we construct a cohomological version of the Connes-Tsygan bicomplex in cyclic homology. As an application of the cyclic Formality conjecture, we ...
متن کاملFORMALITY CONJECTURE by Maxim Kontsevich
This paper is devoted to a conjecture concerning the deformation quantization. This conjecture implies that arbitrary smooth Poisson manifold can be formally quantized, and the equivalence class of the resulting algebra is canonically defined. In other terms, it means that non-commutative geometry, in the formal approximation to the commutative geometry of smooth spaces, is described by the sem...
متن کاملA Proof of the Tsygan Formality Conjecture for Chains
We extend the Kontsevich formality L∞-morphism U : T • poly(R ) → D poly(R ) to an L∞-morphism of an L∞-modules over T • poly(R ), Û : C•(A, A) → Ω(R), A = C(R). The construction of the map Û is given in Kontsevich-type integrals. The conjecture that such an L∞-morphism exists is due to Boris Tsygan [Ts]. As an application, we obtain an explicit formula for isomorphism A∗/[A∗, A∗] ∼ → A/{A, A} ...
متن کاملFormality and Star Products
These notes, based on the mini-course given at the PQR2003 Euroschool held in Brussels in 2003, aim to review Kontsevich’s formality theorem together with his formula for the star product on a given Poisson manifold. A brief introduction to the employed mathematical tools and physical motivations is also given.
متن کاملFormality theorem on infinite-dimensional spaces and a conjecture of B.Feigin
Let An be the free associative algebra with n generators over C, consider the Lie algebra A1 of its outer derivations (the derivations modulo the inner derivations). Let A0 be its quasi-classical limit, that it the Lie algebra of outer derivations of the free Poisson algebra with n generators over C. Boris Feigin conjectured around 1998 that the Lie algebras A0 and A1 are isomorphic. It turns o...
