a constant. We obtain the solution of this equation, which is related to
the spectrum and the kernel, the so called generalized Bessel diamond
heat kernel. Moreover, the generalized Bessel diamond heat kernel is
shown to have interesting properties and to be related to the kernel of
an extension of the heat equatio
