We present a theory for carrying out homogenization limits for quadratic functions (called "energy densities") of solutions of initial value problems (IVPs) with anti-self-adjoint (spatial) pseudo-differential operators (PDOs). The approach is based on the introduction of phase space Wigner (matrix)
