Sporadic and Exceptional

Regular Seminar Yang-Hui He (City)

14:00 QMW
room G.O. Jones 610

We study the web of correspondences linking the exceptional Lie algebras E8,7,6 and the sporadic simple groups Monster, Baby and the largest Fischer group. We will survey some old observations from the perspective of Moonshine and representation theory and present some new ones from that of congruence groups and enumerative geometry. Based on joint work with John McKay.
