一类非线性抛物方程组解的全局熄灭问题

GLOBAL DIE-OUT PROBLEM FOR THE SOLUTIONS OF A CLASS NONLINEAR PARABOLIC SYSTEM

证明了一类非线性抛物方程组的初值问题和具有齐次边值条件的边值问题的解将在有限时刻全局熄灭，并给出了全局熄灭的时间估计。

This paper proves the solutions of the initial value problems and initial boundary value problems with homogeneous boundary conditions of a class nonlinear parabolic system will globally die out at finite time, and some estimate for the die out time are obtained.
