Multivalued behavior for a two-level system using Homotopy Analysis Method

We use the Homotopy Analysis Method (HAM) to solve the system of equations modeling the two-level system and extract results which will pinpoint to turbulent behavior. We look at multivalued solutions as indicative of turbulence or turbulent-like behavior. We take different specific cases which result in multivalued velocities. The solutions are in series form and application of HAM ensures convergence in some region.
