25th Internet Seminar: "Spectral theory for Operators and Semigroups"

This year's topic is “Spectral theory for operators and semigroups” and is suited for master students, Ph.D. students and young post-docs with a basic knowledge on functional analysis and complex analysis of one variable.

As usual (and as many of you may know), the ISem has three phases:

- Phase 1 (October 2021 to February 2022): A weekly lecture will be provided via the ISem website. This material forms a proper self-contained course with study material and exercises. There will also be a forum to discuss the material.

- Phase 2 (March 2022 to June 2022): You will have the chance to work on projects in small international groups. Of course, there will be a supervisor for each project.

- Phase 3 (June 20 to June 25, 2022): There will be a final one-week workshop in Salerno (Italy), where the project teams of Phase 2 will present their projects and additional lectures will be delivered by leading experts.

Registration will open by early September and will be possible until the mid/end of October.
