摘要 研究了一类带有非线性边界条件的非线性抛物型方程组解的整体存在及解在有限时刻爆破问题.通过构造方程组的上、下解,得到了解整体存在的一个充分条件及解在有限时刻爆破的一个充分条件. The global existence and blow up time problem for solutions of a parabolic equations with nonlinear boundary conditions are studied. Using the method of upper-under solutions of the euqations, two sufficient conditions for the global existence and blow up problem are obtained.
