  A new model for the joint neutrino flavor and plasma oscillations is
introduced, in terms of the dynamics of the neutrino flavor polarization vector
in a plasma background. Fundamental solutions are found for both time-invariant
and time-dependent media, considering slow and fast variations of the electron
plasma density. The model is shown to be described by a generalized Hamiltonian
formalism. In the case of a broad spectrum of electron plasma waves, a
statistical approach indicate the shift of both equilibrium value and frequency
oscillation of flavor coherence, due to the existence of a turbulent plasma
background.
