Abstract: In this paper, we are concerned with the existence of the positive bounded and blow-up radial solutions of the (k1,k2)-Hessian system {G(K1k11)K1k11=b1(|x|)g1(z1,z2),  xRN,G(K1k22)K1k22=b2(|x|)g2(z1,z2),  xRN,

where G is a nonlinear operator, Ki=Ski(λ(D2zi))+ψi(|x|)|zi|ki,i=1,2. Under the appropriate conditions on g1 and g2, our main results are obtained by using the monotone iterative method and the Arzela-Ascoli theorem. Furthermore, our main results also extend the previous existence results for both the single equation and systems.

Key words: (k1,k2)-Hessian system, nonlinear operator, blow-up, monotone iterative method, gradient
