一类非线性高阶双曲型方程与非线性高阶抛物型方程解的爆破性质

Blow up of solution to the nonlinear hyperbolic equation of higher order and nonlinear parabolic equations of higher order

本文研究了某一类非线性高阶双曲型方程与非线性高阶抛物型方程，证明了它们的解必在某一有限时刻blowup。

In this paper author has studied the nonlinear hyperbolic equations of higher order andnonlinear parabolic equations of higher order, proved that the solution of the problems are sure to blowup at a certain time.
