# Seminar: Gauge Theory/Eichtheorie (Wintersemester 2020/21)

In the winter semester 2020/21, I will ran a seminar on gauge theory. Gauge theory is vast topic with a long history and an area of a lot of current research. This seminar covered only a small but important part of this subject. The plan for this seminar was to build up the geometric and analytic foundations of gauge theory in dimension four, and to discuss the proof of Donaldson's diagonalization theorem.
