On L-infinity morphisms of cyclic chains
Alberto S. Cattaneo, Giovanni Felder, Thomas Willwacher
Recently the first two authors constructed an L-infinity morphism using the S^1-equivariant version of the Poisson Sigma Model (PSM). Its role in deformation quantization was not e…
On the (ir)rationality of Kontsevich weights
Giovanni Felder, Thomas Willwacher
We compute the weight of a Kontsevich graph in deformation quantization. Up to rationals, the result is Zeta(3)^2/Pi^6.
Formality of cyclic cochains
Thomas Willwacher, Damien Calaque
We prove Kontsevich's cyclic formality conjecture.
Formality of Cyclic Chains
Thomas Willwacher
We prove a conjecture raised by Tsygan, namely the existence of an L-infinity-quasiisomorphism of L-infinity-modules between the cyclic chain complex of smooth functions on a manif…
Cyclic Cohomology of the Weyl Algebra
Thomas Willwacher
We give an explicit formula for symplectically basic representatives of the cyclic cohomology of the Weyl algebra. This paper can be seen as cyclic addendum to the paper by Feigin,…
