✦ Synopsis

Mixed finite element methods axe considered to approximate the solution of fully nonlinear second order parabolic problems in divergence form in •d d _~ 3. Existence and uniqueness of the approximation ave proved. Optimal order error estimates in L~Z(.]; L2(~)) and in L c~ (J; H(div; ~t)) are demonstrated for the relevant variables. Keywords--Nonlineax parabolic problems, Mixed methods, Error estimates.
