Existence of solution for a nonlocal dispersal model with nonlocal term via bifurcation theory

In this paper we study the existence of solution for the following class of nonlocal problems $$L_0u =u \left(\lambda - \int_{\Omega}Q(x,y) |u(y)|^p dy \right) , \ \mbox{in} \ \Omega,$$ where $\Omega \subset \mathbb{R}^{N}$, $N\geq 1$, is a bounded connected open, $p>0$, $\lambda$ is a real parameter, $Q:\Omega \times \Omega \to \mathbb{R}$ is a nonnegative function, and $L_0 : C(\overline{\Omega}) \to (\overline{\Omega})$ is a nonlocal dispersal operator. The existence of solution is obtained via bifurcation theory.
