We study the holomorphic unitary representations of the Jacobi group based on Siegel-Jacobi domains. Explicit polynomial orthonormal bases of the Fock spaces based on the Siegel-Jacobi disk are obtained. The scalar holomorphic discrete series of the Jacobi group for the Siegel-Jacobi disk is constructed and polynomial …

We underline some differences between the geometric aspect of Berezin's approach to quantization on homogeneous Kähler manifolds and Bergman's construction for bounded domains in Cn\mathbb{C}^n. We construct explicitly the Bergman representative coordinates for the Siegel-Jacobi disk D1J\mathcal{D}^J_1, which is a parti…

The coherent state representation of the Jacobi group G1JG^J_1 is indexed with two parameters, μ(=1)μ(=\frac{1}{\hbar}), describing the part coming from the Heisenberg group, and kk, characterizing the positive discrete series representation of SU(1,1)\text{SU}(1,1). The Ricci form, the scalar curvature and the geodesics of th…

Let N\mathcal{N} be the space of Gaussian distribution functions over R\mathbb{R}, regarded as a 2-dimensional statistical manifold parameterized by the mean μμ and the deviation σσ. In this paper we show that the tangent bundle of N\mathcal{N}, endowed with its natural Kähler structure, is the Siegel-Jacobi space…

We determine the homogeneous Kähler diffeomorphism FCFC which expresses the Kähler two-form on the Siegel-Jacobi ball $\mc{D}^J_n=\C^n\times \mc{D}_n$ as the sum of the Kähler two-form on $\C^n$ and the one on the Siegel ball $\mc{D}_n$.
