Дата и място: Tuesday, May 12-th, 13:00, room 403 IMI-BAS. Лектор: Ina Petkova (Darmouth College) Заглавие: Khovanov homology and Lagrangian cobordisms Резюме: We provide a partial answer to a question of Ekholm, Honda, and Kalman about the relationship between Khovanov homology and decomposable Lagrangian cobordisms. We also utilize previously defined filtered invariants to give a family of obstructions to decomposable Lagrangian cobordisms from Khovanov homology. Joint with Gage Martin and Zachary Winkeler.

Поредната сбирка на Националния семинар по стохастика ще се проведе на 12 май 2026 г. (вторник) от 14:00 часа в зала 503 на ИМИ - БАН. Доклад на тема Random Flights and Anomalous Diffusion: A non-Markovian Take on Lorentz Processes ще изнесе Lorenzo Facciaroni (Sapienza University of Rome). Abstract: A Lorentz process is a model for the motion of a particle among randomly located scatterers, also known as obstacles. It was originally used to describe the transport of electrons through a conductor. In the classical setting, when the scatterers are distributed according to a Poisson point process, the deterministic dynamics of elastic collisions can be approximated, under the Boltzmann-Grad scaling limit, by a Markovian random flight. The density of this limiting process is governed [...]
