Massless fields over $R^1\times H^3$ space-time and coherent states for the Lorentz group

Abstract

The solutions of the arbitrary-spin massless wave equations over ${\mathbf{R}}^1\times H^3$ space are obtained using the generalized coherent states for the Lorentz group. The use of these solutions for the construction of invariant propagators of quantized massless fields with an arbitrary spin over the ${\mathbf{R}}^1\times H^3$ space is considered. The expression for the scalar propagator is obtained in the explicit form.
