Towards a Nonperturbative Covariant Regularization in 4D Quantum Field Theory
H. Grosse, A. Strohmaier
Abstract
We give a noncommutative version of the complex projective space CP2 and show that scalar QFT on this space is free of UV divergencies. The tools necessary to investigate Quantum fields on this fuzzy CP2 are developed and possibilities to introduce spinors and Dirac operators are discussed.
