次临界半线性椭圆型方程的定量局部界

Quantitative Local Bounds for Subcritical Semilinear Elliptic Equations

Matteo Bonforte, Gabriele Grillo, Juan Luis Vazquez

摘要:

本文的目的是证明半线性椭圆型方程的弱解的局部上下下界的形式$-Δu= c u^p$,与$0<p<p_s=(d+2)/(d-2)$,定义在有界区域上的$\RR^d$,$d\ge 3$,没有参考的边界行为。我们给出了所有涉及的常数的显式表达式。作为结果,我们得到了局部Harnack不等式与显式常数,以及梯度界。

英文摘要:

The purpose of this paper is to prove local upper and lower bounds for weak solutions of semilinear elliptic equations of the form $-Δu= c u^p$, with $0<p<p_s=(d+2)/(d-2)$, defined on bounded domains of $\RR^d$, $d\ge 3$, without reference to the boundary behaviour. We give an explicit expression for all the involved constants. As a consequence, we obtain local Harnack inequalities with explicit constant, as well as gradient bounds.
