Benoit Charbonneau (Waterloo, Canada) will speak in the differential geometry seminar at 2pm in the Salle des Profs on 20/11/2023. Benoit’s title is “Symmetric instantons” and his abstract is below.
With Spencer Whitehead, we developed a systematic framework to study instantons on R4 that are invariant under groups of isometries. In this presentation, I will describe this framework and some results obtained using it.
