Classification and Reduction of Homogeneous Star Products

Marvin Dippell, Chiara Esposito, Jonas Schnitzer

We present a classification of homogeneous star products on duals of Lie algebroids in terms of the second Lie algebroid cohomology. Moreover, we extend this classification to proj…

Infinitesimal Star Products Compatible with Coisotropic Reduction

Marvin Dippell

We determine infinitesimal star products on Poisson manifolds compatible with coisotropic reduction. This is achieved by computing the second constraint Hochschild cohomology of th…

Global Homotopies for Differential Hochschild Cohomologies

Marvin Dippell, Chiara Esposito, Jonas Schnitzer +1

We construct explicit global homotopies for differential Hochschild cochains in differential geometry, thereby upgrading the classical Hochschild-Kostant-Rosenberg map to a deforma…

Constraint Vector Bundles and Reduction of Lie (Bi-)Algebroids

Marvin Dippell, David Kern

We present a framework for the reduction of various geometric structures extending the classical coisotropic Poisson reduction. For this we introduce constraint manifolds and const…

Constraint Reduction in Algebra, Geometry and Deformation Theory

Marvin Dippell

To study coisotropic reduction in the context of deformation quantization we introduce constraint manifolds and constraint algebras as the basic objects encoding the additional inf…

A Serre-Swan Theorem for Coisotropic Algebras

Marvin Dippell, Felix Menke, Stefan Waldmann

Coisotropic algebras are used to formalize coisotropic reduction in Poisson geometry as well as in deformation quantization and find applications in various other fields as well. I…

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…

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…
