### The fuzzy space-time

Seminar Room 1, Newton Institute

#### Abstract

We reconsider the fuzzyness of 2-dim noncommutative Minkowski space-time in terms of the `harmonic' basis. Fermionic representations of the Lorentz group GL(1,R) appears naturally. The universality of the nonabelain GL(1,R) and GL(N,R) gauge theories are discussed also. We also consider the field theory on this space-time
