Positive solutions of critical Hardy-H\'{e}non equations with logarithmic term
Abstract
We consider the existence, non-existence and multiplicity of positive solutions to the following critical Hardy-H\'{e}non equation with logarithmic term \begin{equation*}\label{eq11}\left\{ \begin{array}{ll} -\Delta u =|x|^{\alpha}|u|^{2^*_{\alpha}-2}\cdot u+\mu u\log u^2+\lambda u, &x\in \Omega,\\ u=0, &x\in \partial \Omega,\\ \end{array} \right.\end{equation*} where for , for , is an unit ball, , , is the critical exponent for the embedding , and which can be seen as a Br\'{e}zis-Nirenberg problem. When and , we will show that the above problem has a positive Mountain pass solution, which is also a ground state solution. At the same time, when , under some assumptions on the , , and , we will show that the above problem has at least a positive least energy solution and at least a positive Mountain pass solution, respectively. What's more, when certain inequality related to , and holds, we will demonstrate the non-existence of positive solutions to the above-mentioned problem. The presence of logarithmic term brings some new and interesting phenomena to this problem.
