Title:
Donaldson And Seiberg-Witten Invariants Of Four-Manifolds From The Physical Viewpoint

Speaker:
Gregory Moore

Abstract:
We will review some work done 20 and 30 years ago by physicists, most notably by Witten, on the formulation of four-manifold invariants using methods of quantum field theory. We first review the general formulation of cohomological topological quantum field theory, and how twisted N=2 field theories fit in that paradigm. Then we review briefly some
