In this paper, we study the positive solutions of the Schrödinger elliptic system div(G(|∇y| p−2)∇y) = b 1 (|x|)ψ(y) + h 1 (|x|)ϕ(z), x ∈ R n (n ≥ 3), div(G(|∇z| p−2)∇z) = b 2 (|x|)ψ(z) + h 2 (|x|)ϕ(y), x ∈ R n , where G is a nonlinear operator. By using the monotone iterative technique and Arzela-Ascoli theorem, we prove that the system has the positive entire bounded radial solutions. Then, we establish the results for the existence and nonexistence of the positive entire blow-up radial solutions for the nonlinear Schrödinger elliptic system involving a nonlinear operator. Finally, three examples are given to illustrate our results.
