Path Integral Approach to Noncommutative Space-Times

Abstract

We propose a path integral formulation of noncommutative generalizations of spacetime manifold in even dimensions, characterized by a length scale $\lambda_P$. The commutative case is obtained in the limit $\lambda_P=0$.Comment: Latex, 12 pages, updated version published in Journal of Mathematical Physics, 39, 2584-2591, 199
