Location: D2 314
Organizer: Prof. Dr. Jürgen Klüners

Title: Frobenius and Octopus

Abstract: We count semisimple nxn-matrices over a finite field F_q that commute with their (p-th power) Frobenius conjugate (for fixed n and for q going to infinity). This involves some linear algebra, algebraic geometry, and graph theory.
