Nontrivial solutions to the Dirichlet problems for semilinear degenerate elliptic equations

Duong Trong Luyen, Nguyen Minh Tri, Dang Anh Tuan

In this article, we study the existence of non-trivial weak solutions for the following boundary-value problem \begin{gather*} -\frac{\partial^2 u}{\partial x^2} -\left|x\right|^{2…
