Approximate Closed-Form Solutions for the Rabinovich System via the Optimal Auxiliary Functions Method

, 2022
Based on some geometrical properties (symmetries and global analytic first integrals) of the Rabinovich system the closed-form solutions of the equations have been established. The chaotic behaviors are excepted.
