Event description:
“McKay correspondence establishes a bijection between finite subgroups $G$ in $SU(2)$ and simply-laced affine Dynkin diagrams. In this work, we show how one can explicitly construct the corresponding affine root system using the derived category of $G$-equivariant sheaves on $P^1$”
