"Sporadic and Exceptional"



Jueves 20 de abril, 10:30
Módulo 17, sala 520

Resumen: There tends to be exceptional structures in classifications: in geometry, there are the Platonic solids; in algebra, there are the exceptional Lie algebras; in group theory, there are the sporadic groups, to name but a few.
Could these exceptional structures be related in some way? A champion for such Correspondences is Prof. John McKay.
We take a casual promenade in this land of exceptionology, reviewing some classic results and presenting some new ones based on joint work with Prof. McKay.
