TitleIrreducible constituents of monomial representations
Author(s) Andrea Previtali
TypeArticle in Journal
AbstractWe describe an algorithm for obtaining the central primitive idempotents of the algebra associated with a monomial representation. As a consequence, we obtain its irreducible constituents. This is implemented in Magma, using an algorithm based on Dixon’s modular approach. In the case of permutation representations, we get a simplified version of the algorithms of Michler and Weller.
