摘要: In this talk, we will introduce a work with Yi Ru-Ya Zhang and Yuan Zhou about the regularity and Liouville property for stable solutions to semilinear elliptic equations $-\Deltau=f(u)$. When dimension $n\le 9$ and $f$ changes sign, we study the boundednees for stable solutions. When $n\ge10$ and $f$ is nonnegative, we also give the sharp BMO regularity and Morrey regularity for stable solutions. In particular, as an application, we show a sharp Liouville property for stable solutions.
