SEMINAR: Groups and Combinatorics Seminar: Cyclotomic difference sets

Title: Cyclotomic difference sets

Abstract: The study of cyclotomic difference sets dates back to Paley in 1930s ' and has become well-known for its connection to the long-standing conjecture that every finite flag-transitive projective plane is Desarguesian. In this talk, I will propose a new approach to this classic problem, which gives insights from character sums, $p$-adic gamma functions and systems of polynomial equations.
