Let \(\Omega \) be a \(C^1\) open bounded domain in \(\mathbb {R}^N, \, N\ge 3,\) with \(0\in \bar{\Omega }.\) We consider the following problem involving Hardy–Sobolev critical exponents: $$\begin{aligned} (P)\qquad \qquad {\left\{ \begin{array}{ll} \textstyle \Delta u+\lambda \frac{u^p}{|x|^{s_1}}+\frac{u^{2^*(s_2)-1}}{|x|^{s_2}}=0 \quad \hbox {in}\,\,\,\Omega ,\\ \textstyle u(x)>0\,\hbox {in}\,\,\,\Omega ; \,\,\, u(x)=0\,\,\quad \hbox {on}\,\,\partial \Omega , \end{array}\right. } \end{aligned}$$
