The next meeting of the Joint Seminar of Analysis, Geometry and Topology Department will be held on April 4, 2023 at 2:00 pm (UTC+3)  in Room 478 of IMI.

A talk on:

Introduction to spectral graph theory

 will be delivered by Peter Petrov, Institute of Mathematics and Informatics, Bulgarian Academy of Sciences.

Everybody is invited.

Abstract. This is the first lecture of a series of 2-3 lectures on algebraic graph theory. A very basic knowledge in linear algebra should be enough as a prerequisite, so that the talk could be understood by people from informatics or biology, also by students. Simple examples will accompany any notion. All knowledge needed from graph theory will be given. The Laplacian of a simple graph will be defined, showing in particular how it could be calculated and what for it could be used
