摘要
本文用凸性方法研究了一类多维拟线性抛物型方程: 具有两类边界条件的混合问题解的blow—up性质,得到了其解必在有限时间内blow—u的充分条件。
In this paper,by the convex method we study blow-up solution to mixed problem with double boundary condition for the class of quasilinear multidimensional parabolic differential equation,and have obtained sufficient conditions under which the solution of this class of equation bloiw up within a finite span of time.
