变系数对半线性heat equations方程解的整体存在性的影响

Influence of variable coefficients on global existence of solutions of semilinear heat equations with nonlinear boundary conditions

Alexander Gladkov, Mohammed Guedda

摘要:

本文考虑具有非线性边界条件的半线性抛物型方程。我们给出的条件,保证整体存在的解决方案以及爆破在有限时间内的所有解决方案与非平凡的初始数据。结果取决于变系数的行为,如$t \to \infty.$

英文摘要:

We consider semilinear parabolic equations with nonlinear boundary conditions. We give conditions which guarantee global existence of solutions as well as blow-up in finite time of all solutions with nontrivial initial data. The results depend on the behavior of variable coefficients as $t \to \infty.$
