一个带非线性项的退化四阶抛物方程弱解的存在性

The Existence of Weak Solution for a Fourth Order Degenerate Parabolic Equation with Nonlinear Item

讨论一个带非线性项的退化四阶抛物方程的初边值问题,在一些初值的假定下,证明了弱解的存在性.

We consider an initial-boundary for a fourth order degenerate parabolic equation with nonlinear item. Under some assumptions on the initial value, we establish the existence of weak solutions by the dicrete-time method.
