Summary: This course is about the applications of gauge theory to the geometry and topology of four-dimensional manifolds. It continues the introduction to mathematical gauge theory taught by one of us (MH) last spring. Students who know the basics of the geometry of (principal) fiber bundles can attend this course, even if they did not attend last semster.
We shall start with a discussion of spinc structures and Dirac operators.
We will give a geometric introduction to smooth four-manifolds, discussing examples, the intersection form, perhaps some homotopy theory of four-manifolds, and embedded surfaces. We then develop the basics of Seiberg-Witten gauge theory on four-manifolds, and
we apply this theory to the study of both topological and geometric properties of four-manifolds. The latter are related to the existence of complex and symplectic structures, and of special Riemannian metrics.
Time permitting, we shall also cover some topics closer to the physics of gauge theories.
