Colloquium: Tuesday, February 22, 2022. Speaker: Shira Zerbib (Iowa State University). Title: “KKM-type theorems and their applications”.

Time: 14:00 Abstract: The KKM theorem, due to Knaster, Kuratowski and Mazurkiewicz in 1929, is a topological lemma reminiscent of Sperner’s lemma and Brouwer’s fixed point theorem. It has numerous applications in combinatorics, discrete geometry, economics, game theory and other areas. Generalizations of this lemma, in…
