In this paper, we study related convolution structures onK/Gcoming fromdeformations of the quotient hypergroup structure by certain functions onKwhich we call partial characters with respect toG. They are usually not probability-preserving, but lead to so-called signed hypergroups onK/G. A first example is provided by the Laguerre convolution on [0, ∞[, which is interpreted as a signed quotient hypergroup convolution derived from the Heisenberg group. Moreover, signed hypergroups associated with the Gelfand pair (U(n, 1),U(n)) are discussed.}}, author = {{Rösler, Margit and Voit, Michael}}, issn = {{0008-414X}}, journal = {{Canadian Journal of Mathematics}}, keywords = {{General Mathematics}}, number = {{1}}, pages = {{96--116}}, publisher = {{Canadian Mathematical Society}}, title = {{{Partial Characters and Signed Quotient Hypergroups}}}, doi = {{10.4153/cjm-1999-006-6}}, volume = {{51}}, year = {{1999}}, }
