The ceremony of awarding the Stefan Banach Medal

We are pleased to invite you to the ceremony of awarding the Stefan Banach Medal to Professor Przemysław Wojtaszczyk, which will be held at the Institute of Mathematics of the Polish Academy of Sciences on October 19, 2023 at 3.30 p.m. in room 321 (3rd floor) at Śniadeckich 8 in Warsaw, preceded by the Laureate’s lecture at 2.30 p.m.

Schedule of the award ceremony:

2.30 p.m. - Laureate's lecture in room 321

3.30 p.m. - award ceremony in room 321

Title of the lecture: Greedy methods and democracy in approximation theory and functional analysis

Abstract: According to Wikipedia  "A greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage." In the talk I will present some basic algorithms of this type used in approximation theory. In particular I will discuss such algorithms and their results in the case when a Banach space $X$ has a basis $(x_j)_{j=1}^\infty$ and we want to approximate an element $x\in X$ as well as possible using only a fixed number of $x_j$'s.
