Popis: We consider the following semilinear problem \begin{equation*} \begin{cases} -\Delta u(x)=a(x)u^{\sigma }(x),\text{ }x\in \Omega \backslash \{0\}\text{ (in the distributional sense),} \\ u>0,\text{ in }\Omega \backslash \{0\},\\ \underset{\left\vert x\right\vert \rightarrow 0}{\lim }\left\vert x\right\vert ^{n-2}u(x)=0, \\ u(x)=0,\text{ }x\in \partial \Omega , \end{cases}% \end{equation*} where $\sigma
