Seminar: "An estimation of the metric for the wreath product of two groups" (Eric López, UPC)

Date: Thursday March 27th, 16-17.
Place: CRM, room C1/028
Títle: "An estimation of the metric for the wreath product of two groups".
Speaker: Eric Lopez, UPC.

Abstract: The aim of this talk is to present an estimation of the metric in the wreath product of two groups for which we have the respective estimations. With that in mind, we will first review the concept of wreath product and show some of its properties. Then we will study the case of the Lamplighter Group, for which the metric is known exactly, and extend the same method to an estimation for a general wreath product.
Finally, we will use the estimation to study the distortion of some natural subgroups of a wreath product.
