Noncommutative Geometry and Physics: Fundamental Structure of Space and Time

The Fuzzy Space-Time

Author: Ki-Myeong Lee (KIAS)


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
