关于带吸收项的非线性抛物型方程最大解的注记

A note on maximal solutions of nonlinear parabolic equations with absorption

Laurent Veron

摘要:

若$Ω$是$\mathbb R^N$中的有界区域,$f$是在无穷远处满足超线性增长条件的连续增函数,我们研究了问题(P):$\partial_tu-Δu+f(u)=0$在$Q_\infty^Ω:=Ω\times (0,\infty)$上,$u=\infty$在抛物边界$\partial_{p}Q$上解的存在唯一性.我们证明了在大多数情况下,在$Ω$中相关的平稳方程的存在性和唯一性被简化为相同的性质。

英文摘要:

If $Ω$ is a bounded domain in $\mathbb R^N$ and $f$ a continuous increasing function satisfying a super linear growth condition at infinity, we study the existence and uniqueness of solutions for the problem (P): $\partial_tu-Δu+f(u)=0$ in $Q_\infty^Ω:=Ω\times (0,\infty)$, $u=\infty$ on the parabolic boundary $\partial_{p}Q$. We prove that in most cases, the existence and uniqueness is reduced to the same property for the associated stationary equation in $Ω$.
