Abstract: In this study, we introduce two finite-dimensional Lie-Poisson Hamiltonian systems related to the Manakov equation through the nonlinearization method. Additionally, we apply the separation of variables on the common level set of Casimir functions to analyze these systems, which are related to the non-hyperelliptic algebraic curve. Ultimately, we construct the action-angle variables for these systems based on the Hamilton-Jacobi theory and derive the Jacobi inversion problem for the Manakov equation.

Key words: Manakov equation, Non-hyperelliptic algebraic curve, Separation of variables, Action-angle variables
