Discrete mathematics seminar - Which finite groups are filled?

Dates
Wednesday, June 8, 2022 - 14:00 to 15:00

Speaker: Chimere Anabanti (University of Pretoria, South Africa)

Abstract:  A non-empty subset S of a group G is called a product-free set if S and SS have no element in common. Let S be a maximal by inclusion product-free set in a finite group G. We say that S fills G if every non-identity element of G is contained in the union of S and SS. A finite group G is called a filled group if every maximal by inclusion product-free set in G fills G. In this talk, we shall give an application of product-free sets to combinatorics, as well as discuss the known finite filled groups. 

Part of this presentation is a joint work with Sarah Hart and Grahame Erskine.
