Introduction. This paper is devoted to studying global anomalies in the worldsheet path integral of Type II superstring theory in the presence of D-branes. We will not consider orientifolds (or Type I superstrings) and so our string worldsheets will be oriented Riemann surfaces, mapped to a spacetime manifold Y, which is endowed with a spin structure since the model contains fermions. The first case to consider is that of closed worldsheets, without boundary. In this case, global anomalies… CONTINUE READING
