The Homotopy Class of twisted -morphisms
Andreas Kraft, Jonas Schnitzer
The global formality of Dolgushev depends on the choice of a torsion-free covariant derivative. We prove that the globalized formalities with respect to two different covariant der…
The Strong Homotopy Structure of Poisson Reduction
Chiara Esposito, Andreas Kraft, Jonas Schnitzer
In this paper we propose a reduction scheme for multivector fields phrased in terms of -morphisms. Using well-know geometric properties of the reduced manifolds we perfor…
Characteristic (Fedosov-)class of a twist constructed by Drinfel'd
Jonas Schnitzer
In a seminal paper Drinfel'd explained how to associate to every classical r-matrix for a Lie algebra $\lie g$ a twisting element based on $\mathcal{U}(\lie g)[[\hbar]]$, or equiva…
A proof of Tsygan's formality conjecture for Hamiltonian actions
Chiara Esposito, Niek de Kleijn, Jonas Schnitzer
In this short note we prove an equivariant version of the formality of multidiffirential operators for a proper Lie group action. More precisely, we show that the equivariant Hochs…
