Peter Wong (Bates College, Lewiston, Maine, USA) visited Charlotte Scott Centre for Algebra

From 6th to the 9th of December 2023, the Charlotte Scott Centre for Algebra had the pleasure of welcoming Peter Wong (Bates College, Lewiston, Maine, USA) for a research visit. During his stay, he presented his work at our algebra seminar and had several discussions with Lincoln algebraists on questions of mutual interest.

Talk title: Outer Automorphisms, Character Spheres, and Twisted Conjugacy

Abstract: A group G has property R∞ if every automorphism f of G has infinitely many f-twisted conjugacy classes of elements. In this talk, we revisit some of the existing techniques that have been employed to obtain R∞. We illustrate by means of examples how to extend these methods and still prove R∞ results. This is joint work with P. Sankaran.
