The spectral function (also known as the Plancherel measure), which gi
ves the spectral distribution of the eigenvalues of the Laplace-Beltra
mi operator, is calculated for a field of arbitrary integer spin (i.e.
, for a symmetric traceless and divergence-free tensor field) on the N
-dimensional real hyperbolic space (H(N)). In odd dimensions the spect
ral function mu(lambda) is analytic in the complex lambda plane, while
in even dimensions it is a meromorphic function with simple poles on
the imaginary axis, as in the scalar case. For N even a simple relatio
n between the residues of mu(lambda) at these poles and the (discrete)
degeneracies of the Laplacian on the N sphere (S(N)) is established.
A similar relation between mu(lambda) at discrete imaginary values of
lambda and the degeneracies on S(N) is found to hold for N odd. These
relations are generalizations of known results for the scalar field. T
he zeta functions for fields of integer spin on H(N) are written down.
Then a relation between the integer-spin zeta functions on H(N) and S
(N) is obtained. Applications of the zeta functions presented here to
quantum field theory of integer spin in anti-de Sitter space-time are
pointed out.
