A priori estimates of stable solutions of the general Hardy-Henon equation in the ball
This paper is devoted to the study of semi-stable radial solutions $u\in H^1(B_1)$ of $-Δu=\vert x\vert^αf(u) \mbox{ in } B_1\setminus\lbrace0\rbrace$, where $f\in C^1(\mathbb{R})$ is a general nonlinearity, $α>-2$ and $B_1$ is the unit ball of $\mathbb{R}^N$, $N>1$. We establish the boudness of such solutions for dimensions $2\leq N<10+4α$ and sharp pointwise estimates in the case $N\geq10+4α$. In addition, we provide, for this range of dimensions, a large family of semi-stable radially decreasing unbounded $H^1(B_1)$ solutions.
