On the Determination of Factor Systems of Pua-representations P. M. Van Den Broek

me relation between the factor systems of a group and those of an invariant subgroup

The relation between the factor systems of a group and the factor systems of an invariant subgroup is discussed both for PU and for PUA representations. The results are used to discuss the factor systems of a class of magnetic space groups.

Shubnikov space groups

The finite-dimensional PUA representations of the Shubnikov space groups are discussed using the method of generalised induction given by Shaw and Lever. In particular we derive expressions for the calculation of the little groups.
