Harmonic Analysis on the Finite Twisted Poincaré Upper Half Plane
Jorge Soto-Andrade, Jorge Vargas
Abstract
We prove that the induced representation from a non trivial character of the Coxeter torus of GL(2,F), for a finite field F, is multiplicity-free; we give an explicit description of the corresponding (twisted) spherical functions and a version of the Heisenberg Uncertainty Principle.
