Abstract:
A point in the moduli space is topologically singular if it does not have a neighbourhood homeomorphic to a ball. In 1962 H. E. Rauch obtained the topologically singular points in the moduli space of Riemann surfaces. In this talk we present a proof of Rauch's results using algebraic topology methods.
