  • Abstract We consider the ordinary and noncommutative Dirac-Born-Infeld theories within the open string σ -model. First, we propose a renormalization scheme, hybrid point splitting regularization, that leads directly to the Seiberg-Witten description including the two-form Φ . We also show how such a form appears within the standard renormalization scheme just by some freedom in changing variables. Second, we propose a Wilson factor which has the noncommutative gauge invariance on the classical… CONTINUE READING
