Abstract

We prove that if XX is a symmetric space of the noncompact type, just as adding Helgason waves which propagate in all direction yields an elementary spherical function for XX, a Helgason wave can be produced by adding elementary spherical functions whose centers cluster along a horocycle in XX.
