| Abstract: | Based on appropriate assumptions of nonlinear terms, by use of parabolic regularization method and method of upper and lower solutions, some existence results of solutions to a class of singular nonlinear parabolic equations with initial boundary values on a smooth domain Ω�瘙}�N and some estimates of solutions on the space L2(0, T; W1,20(Ω))∩L∞(0, T; L2(Ω)) are obtained. Moreover, the uniqueness of solutions for two kinds of special problems is also obtained. |
