Deformation quantization of the simplest Poisson orbifold
TL;DR: In this article , the authors consider the case where a given Poisson manifold is equipped with discrete symmetries and show that the corresponding algebra of invariant functions or the algebra of functions twisted by the symmetry group can have new deformations which are not captured by Kontsevich Formality.
Journal ArticleDOI
Correlation Functions of Sp(2n) Invariant Higher-Spin Systems
TL;DR: In this article, the general structure of correlation functions in an Sp(2n)-invariant formulation of systems of an infinite number of higher-spin fields was studied, and it was shown that for n>2 the symmetry and current conservation makes the 3-point correlators of two (rank-one or rank-two) conserved currents with a scalar operator be that of free theory.

Cup product on $A_\infty$-cohomology and deformations
TL;DR: In this article, a method for constructing formal deformations of differential graded algebras in the category of minimal $A_\infty$-algeses is proposed.
Covariant action for conformal higher spin gravity
TL;DR: In this paper , a manifestly covariant and coordinate-independent action for higher spin theories is proposed based on an interplay between higher spin symmetries and deformation quantization: a locally equivalent but manifestly background-independent reformulation, known as the parent system, of the off-shell multiplet of conformal higher spin fields (Fradkin-Tseytlin fields) can be interpreted in terms of Fedosov deformationquantization of the underlying cotangent bundle.
Homotopy Cartan calculus and inner deformations of A ∞ -algebras
TL;DR: In this article , the authors consider inner deformations of families of A ∞ -algebras and prove the invariance of Hochschild (co)homology under inner deformation.
