Irreducible Holomorphic Symplectic manifolds with an action of $Z_{3}^{4} : A_{6}$

Paola Comparin, Romain Demelle, Pablo Quezada Mora

Höhn and Mason classified the possible symplectic groups acting on an Irreducible Holomorphic Symplectic (IHS) manifold of K3 $^{[2]}$ -type, finding that $\mathbb Z_3^4 : \mathcal A…

K3 surfaces with action of the group $M_{20}$

Paola Comparin, Romain Demelle

It was shown by Mukai that the maximum order of a finite group acting faithfully and symplectically on a K3 surface is 960 and if such a group has order 960, then it is isomorphic…
