Introduction to the Ekedahl Invariants

Ivan Martino

Published 2013-12-23, updated 2014-11-18Version 3

In 2009 T. Ekedahl introduced certain cohomological invariants for finite groups. In this work we introduce these invariants and we show some of their properties. We also give an equivalent definition for such invariants.
