Deformation and Hochschild Cohomology of Coisotropic Algebras
Marvin Dippell, Chiara Esposito, Stefan Waldmann
Coisotropic algebras consist of triples of algebras for which a reduction can be defined and unify in a very algebraic fashion coisotropic reduction in several settings. In this pa…
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…
BRST Reduction of Quantum Algebras with -Involutions
Chiara Esposito, Andreas Kraft, Stefan Waldmann
In this paper we investigate the compatibility of the BRST reduction procedure with the Hermiticity of star products. First, we introduce the generalized notion of abstract BRST al…
Coisotropic Triples, Reduction and Classical Limit
Marvin Dippell, Chiara Esposito, Stefan Waldmann
Coisotropic reduction from Poisson geometry and deformation quantization is cast into a general and unifying algebraic framework: we introduce the notion of coisotropic triples of…
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…
Comparison and Continuity of Wick-type Star Products on certain coadjoint orbits
Chiara Esposito, Philipp Schmitt, Stefan Waldmann
In this paper we discuss continuity properties of the Wick-type star product on the 2-sphere, interpreted as a coadjoint orbit. Star products on coadjoint orbits in general have be…
