一类四阶非线性发展方程解的整体不存在性

The Unexistence of the Global Solutions to a Class of Nonlinear Evolution Equations of Fourth-Order

借助于偏微分方程的一些标准技巧对方程的非线性项进行估计,利用凸性的方法得到一类四阶非线性发展方程整体解的不存在性。

In this paper, we are concerned with the unexistenee of the solutions to a class of nonlinear evolution equations of fourth-order. By applying some standard methods we estimate the non-linear terms ingeniously.And we obtain the unexistenee of the global solutions to the problem throughconcavity theory.
