Query: Group averaging for de Sitter free fields in terms of hyperspherical
  functions   We study the convergence of inner products of free fields over the
homogeneous spaces of the de Sitter group and show that the convergence of
inner products in the of $N$-particle states is defined by the asymptotic
behavior of hypergeometric functions. We calculate the inner product for
two-particle states on the four-dimensional hyperboloid in detail.
