It culminates within the whole evidence of the Weyl personality formulation for representations of compact Lie teams and the Frobenius formulation for characters of permutation teams. tremendous good adapted either for a one-year path in illustration idea and for self reliant examine, this booklet is a superb creation to the topic which, in response to the writer, is exclusive in having "so a lot innate attractiveness so with reference to the surface".
