Abstract
The purpose of this note is to give a description of class 2 representations of the absolute Galois group of a field $k$ of characteristic $0$ which satisfy a certain condition of Kummer type. This description is based on Galois cohomology and on the theory of projective representations of finite abelian groups.
Keywords
