| Abstract: |
| Automorphisms of \[K3\] surfaces were very much studied in the last years. Depending on the action on the holomorphic two form which can be trivial or not, they are called symplectic or non-symplectic. The aim of the talk is to present recent results in the study of non-symplectic automorphisms of 2-power order. In particular in the case of the order 16 I completely describe the families of \[K3\] surfaces carrying such automorphisms and I compute the invariant lattice. |
