Abstract

We show that the Wei-Norman method applied to describe the evolution on the Siegel-Jacobi disk D1J=D1×C1\mathcal{D}^J_1=\mathcal{D}_1\times\mathbb{C}^1, where D1\mathcal{D}_1 denotes the Siegel disk, determined by a hermitian Hamiltonian linear in the generators of the Jacobi group G1JG^J_1 and Berezin's scheme using coherent states give the same equations of quantum and classical motion when are expressed in the coordinates in which the K\"ahler two-form ωD1J\omega_{\mathcal{D}^J_1} can be written as ωD1J=ωD1+ωC1\omega_{\mathcal{D}^J_1}=\omega_{\mathcal{D}_1}+\omega_{\mathbb{C}^1}. The Wei-Norman equations on D1J\mathcal{D}^J_1 are a particular case of equations of motion on the Siegel-Jacobi ball DnJ\mathcal{D}^J_n generated by a hermitian Hamiltonian linear in the generators of the Jacobi group GnJG^J_n obtained in Berezin's approach based on coherent states on DnJ\mathcal{D}^J_n.
