| Abstract: | In this paper, the initial and boundary problems of a sort of degenerateparabolic equations are discussed and an integral estimation is obtained on the upper andlower solutions. Therefore, the existence and uniqueness of the solution is proved and aconclusion is given to the asymptotic behavior of the solution. |
