17th Conference in
Spectral Theory and Mathematical Physics
22–26 June, 2026
The conference is devoted to spectral theory and its applications in modern mathematical physics. There will be talks on the general operator theory, differential, integral and difference operators, scattering theory, inverse problems, periodic and ergodic operators, asymptotic methods and applications, e.g., in the modern quantum physics and nonlinear physics. We also plan to organize talks devoted to interesting general analytic problems.
Although only invited talks will be presented at the conference, everyone is welcome to attend. The meetings will be held in a hybrid format. Participants can join in-person at the Leonhard Euler International Mathematical Institute (Pesochnaya nab. 10, St. Petersburg, Russia), or via Zoom (register to get the link).
Registration Fee
A registration fee of 1500 RUB is required for all in-person attendees, except for students, PhD candidates and young researchers. The fee will cover participation in social events. Payment is accepted online through the SPbSU webpage until June 7, 2026. There is no registration fee for virtual attendees.
