Title: Tverberg's theorem: different approaches to the colorful version
Abstract: Tverberg's theorem is a classic result on the structure of finite sets of points in R^d. One of the most notable open problems related to it is a colorful version proposed by Barany and Larman in 1992. This problem has been attempted with many topological tools, and different degrees of success. During this talk we will introduce a variation of the colorful version that allows for linear-algebraic methods to work and is closer to Tverberg's original result.
