      1 Introduction

      The aim of this paper is to show the positive radial solutions of the following(k1,k2)-Hessian system involving a nonlinear operator and gradient:

      where N ≥2, G is a nonlinear operator on Λ={G ∈C2([0,+∞),(0,+∞))|, and there exists a constant α >0 such that for all 0 <l <1,G(ls)≤lαG(s)}.

      Inspired by the above works, by using the monotone iterative method, we investigate the existence of entire positive bounded and blow-up radial solutions of the nonlinear (k1,k2)-Hessian system (1.1) involving a nonlinear operator. Our results complement the works of many authors([1–15,18–24]),and are also closely related to some recent works by the iterative method ([25–29]) for various differential equations.
