英文摘要:

      In this paper, we show that the multiplicity of k-admissible radial solutions set of a k-Hessian system with a nonlinear operator and gradients. Based on appropriate assumptions about f_i(i=1,2), several findings concerning the multiplicity of k-admissible radial solutions are established via fixed point index theorem.
