摘要
本文以一种变换。化非线性方程为非线性抛物型方程,并利用凸性方法及最大值原理证明其初边值问题的解于有限时间内blow up. 然后借助于Riemann函数。设计一结构,由此经积分而变原问题为积分微分方程,再依不动点原理证明它与原问题等价,且由该积分微分方程而求得一致收敛的迭代解。
The paper changes the non-linear equation into a non-linear parabolic equation by a kind of change and proves the blow up of solution of its initial boundary value problem in finite time by using convexity method and maximum principle.Then,designing a structure by way of Riemann function, it changes the original problem into an integral and differential equation through integral, proves them equivalent according to fixed-point theorem, and gets the uniformly convergent interative solution on the basis of integral and differential equation.
