On January 22, 2024, Monday, at 1:00 pm, in Room 478 of IMI-BAS, Assoc. Prof. Stoyu Barov will deliver an inaugural lecture on: On closed sets with convex projections in separable Hilbert spaces"   Abstract.  We discuss closed sets in R^n and in Hilbert space l^2 all of whose shadows (projections onto hyperplanes) are convex. Among other theorems,  we show that if C is a closed and nonconvex set in Hilbert space l^2 such that the closures of the projections onto all hyperplanes are convex and proper, then C must contain a closed topological copy of l^2 .

On January 19, 2024, Friday, at 3:30 pm, in Room 503 of IMI-BAS, Prof. Danila Cherkashin will deliver an inaugural lecture on: Decomposition of matrices over an arbitrary field as a sum of periodic matrices and nilpotent matrices of order 2  

On Friday, Kuly 21, 2023, at 2:00 pm (GMT+3) in the Conference Room of IMI-BAS, Assoc. Prof. Danila Cherkashin will deliver an inaugural lecture on: Gilbert—Steiner problem Abstract. Gilbert—Steiner problem lies in the class of mass transportation problem. Consider two finite atomic probablistic measures in the plane. The goal is to construct a network (which is an embedded forest) of the lowest price. The price functional is the some over the roads (the edges of the forest) of its capacity in the power a, which is between 0 and 1, mutiplied on the length. We give an introduction in the problem and prove that a solution do not contain branching point of degree 4. The lecture will be streamed via Zoom:  https://us02web.zoom.us/j/83111372029?pwd=MzE5WGRBMHkyQWVESC9rd2ZjVlVmQT09 .   [...]
