Some observations on mixed methods for fully nonlinear parabolic problems in divergence form Original Research Article

Mixed finite element methods are considered to approximate the solution of fully nonlinear second order parabolic problems in divergence form in Rd, d ≤ 3. Existence and uniqueness of the approximation are proved. Optimal order error estimates in L∞ (J; L2(Ω)) and in View the MathML source are demonstrated for the relevant variables.
