Personalpolitik und Mitbestimmunget has the Gelfand pair property explained below. A general setting which encompasses and extends this is that of an association scheme. For any association scheme there is available a character theory, which in the case where the scheme arises from a group coincides with that of group characters. T

There is given an explicit description of the finite groups whose character tables fuse from a cyclic group. Then there is given an account of

Multiplicative Forms on Algebras and the Group Determinant,s back to the search for “sums of squares identities”, the construction of “hypercomplex numbers” and the investigation of quadratic forms. The underlying objects, the group matrix, and its determinant, the group determinant, are introduced. It is shown that group matrices can be constructed as bloc

The book by Davis (Circulant Matrices, Chelsea, New York, 1994) gives a comprehensive account of circulants and the chapter is designed to provide a far reaching extension and generalization of the results there. If an arbitrary subgroup . of a group . is taken, it is shown that with an a

Norm Forms and Group Determinant Factors,tructive approach to the theory of algebras which uses the generalization to noncommutative algebras of a (multiplicative) norm, which can be applied to obtain results on group determinants. This continues a line of research which goes back to Frobenius. Significant results which have not been trans
