All courses for every first-year Science student will be delivered online this fall. A limited number of students in their second, third and fourth years will return to campus for part of the semester.

Colloquium - Pierre Germain - Stability of kinks in one-dimensional Klein-Gordon equations

Description

Title: Stability of kinks in one-dimensional Klein-Gordon equations

Speaker: Pierre Germain (Courant Institute of Mathematical Sciences, NewYork University)
   
Abstract: Kinks are topological solitons, which appear in (nonlinear) one-dimensional Klein-Gordon equations, the Phi-4 and Sine-Gordon equations being the most well-known examples. I will present new results which give asymptotic stability for kinks, with an optimal decay rate, in some cases. The proof relies on the distorted Fourier transform associated to the linearized equation around the kink; this method should be of interest for more general soliton stability problems. This is joint work with Fabio Pusateri.
