A joint seminar of the International Center for Mathematical Sciences and the Department of Mathematical Foundations of Informatics will be held on Tuesday, March 7, 2023, at 2:00 pm, in Room 403 of IMI - BAS. Speaker: Dr. Alexandr Polyanskii, IMI - BAS. Title: Plank Problems: Discrete Geometry and Convexity Abstract: The set of points lying between two parallel lines in the plane is called a plank. Given a convex region C in the plane, what is the smallest combined width of a finite collection of planks that cover C? What happens in higher dimensions? In the 50s, Thoger Bang answered this innocent question of Alfred Tarski and opened a box with many deceptively simple-looking problems. In my talk, I will overview progress in the [...]
The next meeting of the seminar of the International Center for Mathematical Sciences will be held on Tuesday, February 28, 2023, at 2:00 pm, in Room 403 of IMI - BAS. Speaker: Dr. Dimitar Kodjabachev, IMI - BAS. Title: Gorenstein rings in stable homotopy theory Abstract. I will discuss a generalization, due to Dwyer, Greenlees and Iyengar, of the notion of a Gorenstein ring from commutative algebra to the algebra of ring spectra. I will illustrate the concept with classical examples from stable homotopy theory as well as more exotic ones coming from derived algebraic geometry, namely the ring spectra of topological modular forms with level structure. Time permitting, I will discuss how things generalize equivariantly in the presence of a group action.

A joint seminar of the International Center for Mathematical Sciences and the Department of Mathematical Foundations of Informatics will be held on Tuesday, January 31, 2023, at 3:00 pm, in Room 403 of IMI - BAS. Speaker: Prof. Nikolaj Glazunov, IMI - BAS, Institute of Cybernetics, Kiev. Title: On optimal packing of Minkowski balls and applications Abstract: We investigate lattice packings of Minkowski balls and domains. By results of the proof of Minkowski conjecture about the critical determinant we divide the balls and domains on 3 classes: Minkowski, Davis and Chebyshev-Cohn. The optimal lattice packings of the balls and domains are obtained. The minimum areas of hexagons inscribed in the balls and domains and circumscribed around them are given. These results lead to algebro-geometric [...]
