Resumen de On the spectrum of the generalized Gelfand pair , (u(p,q)hn), p+q=n

T. Godoy, Linda Saal

• It is known that the spectrum of the Gelfand pair (U(n),Hn) is homeomorphic to the Heisenberg fan. In this paper after defining a suitable notion of spectrum, we prove an analogous result for the generalized Gelfand pair (U(p,q),Hn), p+q=n.
