Query: The classification of purely non-symplectic automorphisms of high order
  on K3 surfaces   An automorphism of order $n$ of a K3 surface is called purely non-symplectic
if it multiplies the holomorphic symplectic form by a primitive $n$-th root of
unity. We give the classification of purely non-symplectic automorphisms with
$\varphi(n)\geq 12$ where $\varphi$ denotes the Euler totient function.
