Abstract
The classical domain of type one has an unbounded realization as the Siegel domainD(Φ, Ω) by the Cayley transform. LetP be the Iwasawa subgroup of the affine automorphisms group ofD(Φ, Ω), thenP has a natural unitary representation U on\(L^2 (\Re )\). We decompose\(L^2 (\Re )\) into the direct sum of the irreducible invariant closed subspaces under U, and give the characterization of the admissible condition in terms of the Fourier transform. Define the wavelet transform, we obtain the direct sum decomposition of L2(D(Φ, Ω), dμ).
