设为一个四阶非线性抛物型方程柯西问题的解,其中。本文给出了解的最大存在时间为有限的一个充分条件。此外,我们证明了,如果,则在处爆破,并且我们得到了爆破率的较低估计。我们也给出了柯西问题的整体时间解存在的一个充分条件。
Letbe a solution to the Cauchy problem for a fourth-order nonlinear parabolic equationon, whereand. In this paper we give a sufficient condition for the maximal existence timeof the solutionto be finite. Furthermore, we show that if, thenblows up at, and we obtain lower estimates on the blow-up rate. We also give a sufficient condition on the existence of global-in-time solutions to the Cauchy problem.
