Description

We discuss U(1) gauge theory with noncommutative space-time coordinates in two and four dimensions on a lattice with N sites. The mapping to a U(N) plaquette model in the sense of Eguchi and Kawai makes both analytical calculations and computer simulations feasible. The topological charge q can be transcribed to the plaquette and hypercube formulation in the matrix theory in 4D. There exist formulations of the classical equation of motion within the matrix model. From them we try to derive general formulae for q in four dimensions. The aim is to analyze an action-charge diagram as in 2D.
