Thomas Poguntke passed away on September 24, 2018, after a serious illness, just a few weeks after arriving in Barcelona. He was 28 years old and about to hand in his PhD thesis (University of Bonn) on higher Segal spaces, Ktheory and Hall algebras.
This workshop is dedicated to his memory and to his mathematics, which will live on. 31 January1 February, 2019, CRM

Speaker: Jesper Moller (University of Copenhagen) Title: Counting psingular elements in finite groups of Lie type Place: Room Seminar C3b Date: Friday January 25, 12h13h
Abstract: Let $G$ be a finite group and $p$ a prime number. We say that an element of $G$ is $p$singular of its order is a power of $p$. Let $G_p$ be the {\em set\/} of $p$singular elements in $G$, i.e. the union of the Sylow $p$subgroups of $G$. In 1907, or even earlier, Frobenius proved that $G_p \mid G_p$: The number of $p$singular elements in $G$ is divisible by the $p$part of the order of $G$. The number of $p$singular elements in a symmetric group is known. In this talk we discuss the number of $p$singular elements in a finite (untwisted) group of Lie type in characteristic $p$. The situation in the crosscharacteristic case will maybe also be considered.
