Let \(\Omega\) be a bounded domain of \(\mathbb{R}^ n\) with boundary \(\Gamma\), \(n\geq 1\). The goal of this note is to summarize results regarding existence and number of solutions of the equation \[ \Delta\varphi- |\nabla \varphi|^ q+ \lambda \varphi^ p=0 \quad \text{in }\Omega, \qquad \varphi>0 \quad \text{in }\Omega, \qquad \varphi=0 \quad \text{on }\Gamma, \tag{1} \] \(\lambda>0\), \(p,q>1\).
