## Sublinear singular elliptic problems with two parameters.(English)Zbl 1039.35042

Let $$\Omega$$ be a smooth bounded domain in $$\mathbb R^N$$ $$(N\geq 2)$$. The authors study the existence or nonexistence of solutions to the following boundary value problem $\begin{cases} -\Delta u+ K(x)g(u)=\lambda f(x,u)+\mu h(x)\quad &\text{in }\Omega,\\ u> 0\quad &\text{in }\Omega,\\ u=0\quad &\text{on }\partial\Omega,\end{cases}\tag{P$$_{\lambda,\mu}$$}$ where $$\lambda$$ and $$\mu$$ are positive parameters. Under suitable assumptions on $$K$$, $$g$$, $$f$$ and $$h$$ the authors using the maximum principle for elliptic equations establish several existence and nonexistence results for $$(\text{P}_{\lambda,\mu})$$.
