A C*-Algebraic Model for Locally Noncommutative Spacetimes
Jakob G. Heller, Nikolai Neumaier, Stefan Waldmann
Locally noncommutative spacetimes provide a refined notion of noncommutative spacetimes where the noncommutativity is present only for small distances. Here we discuss a non-pertur…

Locally Noncommutative Space-Times
Dorothea Bahns, Stefan Waldmann
Localized noncommutative structures for manifolds with connection are constructed based on the use of vertical star products. The model's main feature is that two points that are f…

Formal Deformations of Dirac Structures
Frank Keller, Stefan Waldmann
In this paper we set-up a general framework for a formal deformation theory of Dirac structures. We give a parameterization of formal deformations in terms of two-forms obeying a c…
