We propose a new two-level implicit difference method of O(k 2 + kh 2 + h 4 ) for the solution of singularly perturbed non-linear parabolic differential equation (u xx +u yy )=f (x, y, t, u, u x , u y , u t ), 0 < x, y < 1, t > 0 subject to appropriate initial and Dirichlet boundary conditions, wher
