| Abstract: | It is shown that there are no gravitational, Yang-Mills, local supersymmetry hexagon anomalies in higher genus amplitudes of type II superstring and heterotic string theory in ten dimensions. The nonrenormalization theorem for massless parity-violating higher genus amplitudes is also proved. |
