Projektseminar (Functional Analysis): TBA
Wintersemester 2017/18

SE 2 std. Wed 9:45-11:15 SR11 4.10
The main topic of the seminar will be spectral theory for unbounded/non-self-adjoint operators. These problems arise in the study of nonlinear problems, in particular nonlinear wave equations. More specifically we want to cover Fredholm theory, essential spectra, and stability of essential spectra for these opera
