An Introduction to -Algebras and their Homotopy Theory
Andreas Kraft, Jonas Schnitzer
In this review we give a detailed introduction to the theory of (curved) -algebras and -morphisms. In particular, we recall the notion of (curved) Maurer-Cartan…
The Strong Homotopy Structure of BRST Reduction
Chiara Esposito, Andreas Kraft, Jonas Schnitzer
In this paper we propose a reduction scheme for polydifferential operators phrased in terms of -morphisms. The desired reduction -morphism has been obtained by…
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…
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…
