Topological and Variational Methods for Partial Differential Equations
In recent years, there has been a major impact of topological and variational methods on the study of nonlinear elliptic and parabolic partial differential equations. In particular, surprising results for classical open problems have been obtained with new techniques far beyond the classical approaches. The purpose of the meeting was to provide a forum for these developments and to bring together experts with complementary background
Direct Method of Scaling Spheres for the Laplacian and Fractional Laplacian Equations with Hardy-Henon Type Nonlinearity
In this paper, we focus on the partial differential equation
\begin{equation*}
(-\Delta)^\frac{\alpha}{2} u(x)=f(x,u(x))\;\;\;\;\text{ in }\mathbb{R}^n,
\end{equation*} where . By the direct method of scaling spheres
investigated by Dai and Qin (\cite{dai2023liouville}, \textit{International
Mathematics Research Notices, 2023}), we derive a Liouville-type theorem. This
mildly extends the previous researches on Liouville-type theorem for the
semi-linear equation where the
nonlinearity depends solely on the solution , and covers the
Liouville-type theorem for Hardy-H\'enon equations
