本文证明一类四阶非线性抛物型方程初边值问题整体广义解的存在性和唯一性,以及解的渐近性质,最后给出解爆破的充分条件.
In this paper,we show that the existence and uniqueness of the global generalized solution of a class of initial boundary value problem,prove the asymptotic behavior of solution, and give the sufficient conditions of blow up of the solution.
