Abstract: In this paper the initial and Dirichlet problem for a class of degenerate and singular nonlinear parabolic equations were investigated. This problem was derived from the evolution of a parametric surface by its mean curvature subject to fixed boundary conditions. The existence and uniqueness of viscosity solutions by constructing subsolutions and supersolutions w ere proved.
