National Workshop on Spectral Theory and Spectral Graph Theory
(NWSGT 2026)

About the workshop

The purpose of the workshop is to stimulate research and, in an informal setting, to foster the interaction of researchers in the interface between functional analysis and graph theory. The workshop will provide a forum through which mathematicians may be better informed of the latest developments and newest techniques in functional analysis and graph theory and may exchange ideas with researchers from different parts of India.

Topics covered

•Hilbert spaces

•Operators on Hilbert spaces

•The spectrum of linear operators

•The spectral theory of a compact operator

•Matrix representations of graphs and associated spectra

•Groups acting on graphs

•Graph spectrum via group actions

•Cayley graphs

Invited Lecture on ‘Spectral Extremal Problems’ by Prof. Rajesh Kannan.
