Liouville type theorem for an anisotropic singular model

In this article, we establish a Liouville type theorem for the anisotropic singular problem \sum_{i=1}^{N}\frac{\partial}{\partial x_i}(|\frac{\partial u}{\partial x_i}|^{p_i-2}\frac{\partial u}{\partial x_i})=e^\frac{1}{u}\;\;\mbox{in}\;\;\mathbb{R}^N concerning positive $W^{1,p_i}(\mathbb{R}^N)$ stable solution, provided $N\geq 1$ and $p_i>2$ for all $i=1,2,\dots{N}$.Comment: 7 page
