Oxidation, Reduction and Semi-Classical Limit for Quantum Matrix Geometries
Laura O. Felder, Harold C. Steinacker
Matrix configurations define noncommutative spaces endowed with extra structure including a generalized Laplace operator, and hence a metric structure. Made dynamical via matrix mo…
An Index for Intersecting Branes in Matrix Models
Harold Steinacker, Jochen Zahn
We introduce an index indicating the occurrence of chiral fermions at the intersection of branes in matrix models. This allows to discuss the stability of chiral fermions under per…
Twisted WZW Branes from Twisted REA's
Jacek Pawelczyk, Harold Steinacker, Rafal R. Suszek
Quantum geometry of twisted Wess--Zumino--Witten branes is formulated in the framework of twisted Reflection Equation Algebras. It is demonstrated how the representation theory of…
Finite dimensional unitary representations of quantum Anti-de Sitter groups at roots of unity
Harold Steinacker
We study irreducible unitary \reps of and for a root of unity, which are finite dimensional. Among others, unitary \reps corresponding to all clas…
