Abstract: | LetSp(n, R) be the sympletic group, and letK
n
* be its maximal compact subgroup. ThenG=Sp(n,R)/K
n
* can be realized as the Siegel domain of type one. The square-integrable representation ofG gives the admissible wavelets AW and wavelet transform. The characterization of admissibility condition in terms of the Fourier
transform is given. The Bergman kernel follows from the viewpoint of coherent state. With the Laguerre polynomials, Hermite
polynomials and Jacobi polynomials, two kinds of orthogonal bases for AW are given, and they then give orthogonal decompositions
ofL
2-space on the Siegel domain of type one ℒ(ℋ
n
, |y| *dxdy).
