CONSEQUENCES OF THE FUNDAMENTAL CONJECTURE FOR THE MOTION ON THE SIEGEL–JACOBI DISK
Abstract
We find the homogeneous Kähler diffeomorphism FC which expresses the Kähler two-form on the Siegel–Jacobi domain as the sum of the Kähler two-form on ℂ and the one on the Siegel ball
. The classical motion and quantum evolution on
determined by a linear Hamiltonian in the generators of the Jacobi group
is described by a Riccati equation on
and a linear first-order differential equation in z ∈ ℂ, where H1 denotes the three-dimensional Heisenberg group. When the transformation FC is applied, the first-order differential equation for the variable z ∈ ℂ decouples of the motion on the Siegel disk. Similar considerations are presented for the Siegel–Jacobi space
, where
denotes the Siegel upper half-plane.
