We consider the boundary value problem for the nonlinear Poisson equation with a nonlocal term , . We prove the existence of a positive radial solution when grows linearly in , using Krasnoselskiiés fixed point theorem together with eigenvalue theory. In presence of upper and lower solutions, we consider monotone approximation to solutions.
