The next meeting of the Joint Seminar of Analysis, Geometry and Topology Department will be held
online on  October 19, 2021 at 2:00 p.m. (GMT+3:00).

A talk on:

Index counting theories and  linear stability of  periodic waves

will be delivered by: Sevdzhan Hakkaev, Shumen University.

Everybody is invited.

Abstract. In this talk, we will present some results on the stability of periodic waves. In the models that we will consider, stability problem leads to the study of the spectral problems of the form

and computations of the quantities involved in the stability index.
