  In the present paper we start consideration of anti de Sitter holography in
the general case of the (q+1)-dimensional anti de Sitter bulk with boundary
q-dimensional Minkowski space-time. We present the group-theoretic foundations
that are necessary in our approach. Comparing what is done for q=3 the new
element in the present paper is the presentation of the bulk space as the
homogeneous space G/H = SO(q,2)/SO(q,1), which homogeneous space was studied by
Sekiguchi.
