BCAM Course | Non-self-adjoint operators and their spectra

Date: Mon, Jan 29 - Fri, Feb 2 2024

Hour: 11:00-13:00

Location: Basque Center for Applied Mathematics (BCAM)

Speakers: Nico Schiavone

Register: Registration

A 10-hours course consisting of five 2-hours lessons. It will take place at the Basque Center for Applied Mathematics (BCAM).

General objective:
The course aims to present a general overview of spectral theory for non-self-adjoint operators, as well as modern techniques to exclude the presence of their eigenvalues or confine them (as the Birman-Schwinger principle and the multipliers method).

Prerequisite Knowledge:

This course assumes a primer knowledge in linear algebra, real analysis, and functional analysis.
