SUMMARY:ICMS Seminar
DESCRIPTION:Time and place: Tuesday\, May 12-th\, 13:00\, room 403 IMI-BAS.\nLecturer: Ina Petkova (Darmouth College)\nTitle: Khovanov homology and Lagrangian cobordisms \nAbstract: 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. \n\n\nMore information can be found on the seminar’s web-page:\nhttps://icms.bg/khovanov-homology-and-lagrangian-cobordisms-icms-seminar-talk-by-ina-petkova/\nhttps://icms.bg/category/icms-seminar/

SUMMARY:National Seminar on Probability and Statistics
DESCRIPTION:The next meeting of the \nNational Seminar on Probability and Statistics\n \nwill be held on May 12\, 2026\, at 2:00 p.m. in Room 503 of the Institute of Mathematics and Informatics. \nA talk on: \nRandom Flights and Anomalous Diffusion: A non-Markovian Take on Lorentz Processes\nwill be delivered by \nLorenzo Facciaroni (Sapienza University of Rome). \nAbstract: 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 by the Boltzmann equation. Passing further to the hydrodynamic limit\, one recovers Brownian motion as the macroscopic description of the particle’s position. In this work\, we introduce a new class of point processes that generalizes the Poisson process and we investigate the motion of a particle which collides elastically with obstacles distributed according to this distribution. Unlike the classical case\, the corresponding limiting random flight process is no longer Markovian. Instead\, it exhibits memory effects that lead to superdiffusive behavior. At the macroscopic level\, the particle’s position converges to a continuous superdiffusive process. Within this framework\, we derive a non-local analogue of the Boltzmann equation governing the non-Markovian random flight. Moreover\, we show that the density of the superdiffusive scaling limit satisfies a fractional heat equation\, reflecting the anomalous transport induced by the underlying correlations. \nKeywords: Lorentz process · Boltzmann-Grad limit · Feller semigroups. \nReferences:\n1.

SUMMARY:National Seminar on Probability and Statistics
DESCRIPTION:The next meeting of the \nNational Seminar on Probability and Statistics\n \nwill be held on May 13\, 2026\, at 2:00 p.m. in Room 503 of the Institute of Mathematics and Informatics. \nA talk on: \nSome Properties of Exponential Functionals of Continuous Gaussian Processes\nwill be delivered by \nJosé Alfredo López-Mimbela (Center for Research in Mathematics Guanajuato\, Mexico). \nAbstract: Exponential functionals of random processes are mathematical expressions that typically involve integrating the exponential of a random process over time. These functionals play a significant role in various areas of mathematics and applied sciences\, including probability theory\, statistical mechanics\, and financial mathematics. In this talk\, we discuss some properties of exponential functionals associated with continuous Gaussian processes. The discussion centers on obtaining useful bounds for their cumulative distribution functions\, with particular emphasis on Brownian motion and fractional Brownian motion. \nMore information about the talk can be found on the seminar website:\nhttp://www.math.bas.bg/~statlab/NSPS/

SUMMARY:Digital Culture Seminar
DESCRIPTION:The next meeting of the Digital Culture Seminar \nwill be held on May 19\, 2026 (Tuesday) at 10:00 a.m. in Room 256 of IMI – BAS. \nA talk on: \nCompeting Conceptions of AGI\nwill be delivered by Pei Wang (Temple University\, USA)\, Edior-in-Chief of the Journal of Artificial General Intelligence. \nAbstract: While the term “Artificial General Intelligence” (AGI) has been used to identify a research field for 20 years\, a consensus on its goal remains controversial. These divergent interpretations are not merely philosophical\, as they lead to fundamentally different research agendas and engineering methodologies. In this talk\, the NARS (Non-Axiomatic Reasoning System) project is introduced\, with an outline of its assumptions\, representations\, inference rules\, and working process. NARS offers a fundamentally different vision of AGI than the one implied by today’s LLMs.
