National Seminar on Probability and Statistics

Institute of Mathematics and Informatics, BAS Akad.G.Bonchev St, bl. 8, 1113, Sofia

The next meeting of the National Seminar on Probability and Statistics will be held on April 16, 2024, at 2:00 p.m. in Room 503 of the Institute of Mathematics and Informatics. A talk on: Convergence Rate for Order 1 Markov Random Walks will be delivered by Peter Gaydarov. Abstract. We examine the limiting behaviour of an order 1 Markov random walk in R2, i.e. a walk that remembers its previous step. Provided a certain symmetry of the Markovian condition, under relatively mild conditions we prove convergence to a Brownian motion and bound the rate of convergence. Therefore, an order 1 Markov condition is insufficient to alter the limiting behaviour of a random walk.  

Algebra and Logic Seminar

Institute of Mathematics and Informatics, BAS Akad.G.Bonchev St, bl. 8, 1113, Sofia

The next meeting of the Algebra and Logic Seminar will be held online via Zoom on April 12, 2024 (Friday) at 1:00 pm (UTC+2). A talk on: On an Aspect of Second Quantum Revolution will be delivered by Valentin Iliev, IMI - BAS. Abstract.The 2022 Nobel Prize in Physics has been awarded to Alain Aspect, John Clauser, and Anton Zeilinger for their work in Quantum Theory. Mass media called this event part of second quantum revolution which includes mainly quantum computing and other super-technologies. Here we discuss Alain Aspect's version of Einstein-Podolsky-Rosen thought experiment and show that there exists an internal dependence of the simultaneous measurements made by the two pairs of linear polarizers operated in each leg of the apparatus during this experiment.
