EXISTENCE OF WEAK SOLUTIONS FOR A DOUBLY DEGENERATE FOURTH-ORDER PARABOLIC EQUATION
摘要
Abstract
In this paper,the existence of weak solutions for a doubly degenerate fourth-order parabolic equation is studied.By Galerkin process and energy method,the existence of the weak solutions in the non-degenerate case is proved firstly.On this basis,the existence of weak solutions in the degenerate case is obtained by uniform estimates asymptotic limits for the regularization problem.关键词
