McKay correspondence and the branching law for finite subgroups of ${\mathbf{SL}}_3\mathbb{C}$

Frédéric Butin, Gadi S. Perets

Given $\Gamma$ a finite subgroup of ${\mathbf{SL}}_3\mathbb{C}$, we determine how an arbitrary finite dimensional irreducible representation of ${\mathbf{SL}}_3\mathbb{C}$ decomposes under…
