On deformation theory of quantum vertex algebras
Harald Grosse, Karl-Georg Schlesinger
We study an algebraic deformation problem which captures the data of the general deformation problem for a quantum vertex algebra. We derive a system of coupled equations which is…
The universal envelope of the topological closed string BRST-complex
Harald Grosse, Karl-Georg Schlesinger
We construct a universal envelope for any Poisson- and Gerstenhaber algebra. While the deformation theory of Poisson algebras seems to be partially trivial, results from string- an…
The Eigenfunctions of the q-Harmonic Oscillator on the Quantum Line
Harald Grosse, Stefan Schraml
We construct a complete set of eigenfunctions of the q-deformed harmonic oscillator on the quantum line. In particular the eigenfunctions corresponding to the non-Fock part of the…
A Remark on Topological Charges over the Fuzzy Sphere
Harald Grosse, Christian W. Rupp
We determine the Chern characters of two projective modules over the fuzzy sphere and calculate the corresponding topological charges (Chern numbers). These turn out to have correc…
The energy-momentum tensor on noncommutative spaces - some pedagogical comments
A. Gerhold, J. Grimstrup, H. Grosse +3
We present the discussion of the energy-momentum tensor of the scalar - theory on a noncommutative space. The Noether procedure is performed at the operator level. Additionall…
Renormalization of noncommutative Yang-Mills theories: A simple example
Harald Grosse, Thomas Krajewski, Raimar Wulkenhaar
We prove by explicit calculation that Feynman graphs in noncommutative Yang-Mills theory made of repeated insertions into itself of arbitrarily many one-loop ghost propagator corre…
