We study the existence of a weak (strong) solution of the nonlinear elliptic problem\begin{gather*} -\Delta u- \lambda ug_1 +h(u)g_2=f \quad\text{in}\quad V\setminus V_0,\\u=0 \quad\text{on}\quad V_0,\end{gather*} where $V$ is a Sierpi\'nski gasket in $\mathbb{R}^{N-1},$ $N\geq 2,$ $V_0$ is its boundary (consisting of $N$ its corners), and $\lambda$ is a real parameter. Here, $f,g_1,g_2\colon V\to\mathbb{R}$ and $h\colon \mathbb{R}\to\mathbb{R}$ are functions satisfying suitable hypotheses. |
