Abstract: | The purpose of this paper is to continue the study of induced representations of hypergroups. We introduce the concept of Weil subhypergroups and Weil homomorphisms and derive a Weil formula for kernels of Weil homomorphisms. Making use of this decomposition formula, we prove in the main theorem that lifting a representation via a Weil homomorphism is compatible with the inducing process. As a further consequence we obtain that a character of a supernormal subhypergroup is inducible, if and only if it admits an extension, while in general the extensibility of a character does not imply its inducibility.This research project is supported by the DFG. |
