摘要

The main result of this paper is the explicit construction of algebraic Hecke characters of K3 surfaces defined over a number field \(k\subset \mathbb {C}\) k C with complex multiplication. In particular, we give the explicit determination of the algebraic Hecke characters of Kummer surfaces associated to simple abelian surfaces with complex multiplication.
