Ultra-violet Finite Noncommutative Theories

We establish the ultraviolet finiteness of various classes of noncommutative gauge theories.

The Abiotic Action of Ultra-violet Light

Typhoid bacilli are about one two-hundredth as sensitive to ultraviolet light of wave-lengths 2100 to 2800 Angström units as is the photographic plate. This sensitivity then falls off, decreasing rapidly to almost zero sensitivity at about 2970, the beginning of the sun's spectrum.

Ultra-violet Finiteness in Noncommutative Supersymmetric Theories

We consider the ultraviolet divergence structure of general noncommutative super-symmetric U (N c) gauge theories, and seek theories which are all-orders finite. September 2001
