Projektseminar (Functional Analysis): Stability of nonlinear waves
Wintersemester 2018/19

Time and Place
Type: Time: Place: Start:
SE 2 std. Thu 11:30-13:00 SR07 4.10
Topics
The stability of linear and nonlinear waves has a fascinating history. In this seminar we would like to discuss basic approaches to the problem of stability (spectral, orbital and asymptotic) of solitary waves. Our main aim is to look at a circle of ideas and the mathematical machinery that has been built to investigate the stability problem.
