SUMMARY:National Seminar on Probability and Statistics
DESCRIPTION:The next meeting of the \nNational Seminar on Probability and Statistics\n \nwill be held on April 21\, 2026\, at 2:00 p.m. in Room 503 of the Institute of Mathematics and Informatics. \nA talk on: \nHow long does it take to train an Elephant Random Walk\nwill be delivered by \nZheng Fang (University of Zurich). \nAbstract: We study how conditioning on the first \(k\) steps\, which we think of as training\, affects the long-term behavior of the Elephant Random Walk. When the elephant is conditioned to be at position \(k\) at time \(k\)\, the first return time to the origin scales as \(k^{(4−4p)⁄(3−4p)}\) in the diffusive regime\, and grows exponentially in the critical regime. We loosely interpret this as a measurement of the rate at which the elephant forgets its training. \nMore information about the talk can be found on the seminar website:\nhttp://www.math.bas.bg/~statlab/NSPS/

SUMMARY:Algebra and Logic Seminar
DESCRIPTION:The next meeting of the Algebra and Logic Seminar will take place on April 24\, 2026 (Friday) at 1:00 pm (UTC+3) in Room 578 and online via Zoom. \nA talk on: \nSets preserved by a large subgroup of the special linear group\nwill be delivered by \nKaloyan Slavov (Medical University\, Sofia).\nAbstract. The classical Kakeya problem in Euclidean space asks how “small” a set can be if it contains a unit line segment in every direction. More generally\, packing sets contain all images of a given set under a collection of transformations. Finite field analogues offer a combinatorial and algebraic perspective and motivate our work. \nWe study sets \(E\) in the affine plane over a finite field that are invariant under a large subgroup \(R\) of \(SL_2\). We prove that if \(|R|>c|E|^{3/2}\)\, then \(E\) must be contained in a line. The exponent \(3/2\) is sharp. We conclude with a remark on a related phenomenon in the Euclidean setting. This is joint work with Thang Pham and Le Quang-Hung. \nLink to the zoom meeting:\nhttps://us02web.zoom.us/j/88300991142?pwd=wGYl7VaD9RZKEm99sKzHMzl3bYCv3J.1\nEverybody is invited. \nAlgebra and Logic Department\, IMI – BAS\nhttp://www.math.bas.bg/algebra/seminarAiL/\n============================== =====================

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.
