摘要
讨论一个具有非线性关系的退化四阶抛物方程的初边值问题,在一些初值的假定下,用时间离散化方法证明了弱解的存在性.
The paper, presents an initial - boundary value problem for a fourth order degenerate parabolic equation with nonlinear relation. With assumptions of the initial value, the dicrete - time method is applied to the study of the existerce of weak solutions.
