A Quantum Energy Inequality for a Non-commutative QFT
Harald Grosse, Albert Much
We present a quantum energy inequality (QEI) for quantum field theories formulated in non-commutative spacetimes, extending fundamental energy constraints to this generalized geome…
Noncommutative QFT and Renormalization
Harald Grosse, Michael Wohlgenannt
Field theories on deformed spaces suffer from the IR/UV mixing and renormalization is generically spoiled. In work with R. Wulkenhaar, one of us realized a way to cure this disease…
The Fuzzy Supersphere
Harald Grosse, Gert Reiter
We introduce the fuzzy supersphere as sequence of finite-dimensional, noncommutative -graded algebras tending in a suitable limit to a dense subalgebra of the -graded…
On Finite 4D Quantum Field Theory in Non-Commutative Geometry
H. Grosse, C. Klimcik, P. Presnajder
The truncated 4-dimensional sphere and the action of the self-interacting scalar field on it are constructed. The path integral quantization is performed while simultaneously…
