Gregory W. Moore: Supersymmetric QFT & Invariants Of Smooth Four-Manifolds

Abstract. After describing briefly some aspects of nonabelian Yang-Mills theory and Donaldson invariants  the physicists' derivation of the "Witten conjecture" expressing Donaldson invariants in terms of Seiberg-Witten invariants will be sketched. Time permitting, more recent developments related to this physical approach will be sketched.
