SUMMARY:Съвместен семинар на МЦМН и секция МОИ
DESCRIPTION:Във вторник\, 07.03.2023 г.\, от 14:00 часа в зала 403 ще състои съвместна сбирка на семинарите на\nМЦМН и секция МОИ.\nДоклад на тема:\nPlank Problems: Discrete Geometry and Convexity\nще изнесе д-р Александър Полянский (ИМИ-БАН).\n\n\nAbstract: 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. \nIn my talk\, I will overview progress in the area and its connection with other fields: theoretical computer science\, number theory\, and analysis. In particular\, I will discuss a joint work with Zilin Jiang confirming Fejes Toth’s long-standing zone conjecture and recent results with Alexey Glazyrin and Roman Karasev on a polynomial plank problem\, a far-reaching generalization of Bang’s theorem.
