The existence of a positive solution to the Dirichlet boundary value problem for the second order elliptic equation in divergence form
$-∑_{i,j=1}^{n} D_i(a_{ij}D_ju) = f(u,∫_{Ω}g(u^p))$,
in a bounded domain Ω in ℝⁿ with some growth assumptions on the nonlinear terms f and g is proved. The method based on the Krasnosel'skiĭ Fixed Point Theorem enables us to find many solutions as well.
