Jian Liu, Hua Su, Shuli Wang
2012 Journal of Applied Mathematics  
Under the assumption of two coupled parallel subsuper solutions, the existence of at least six solutions for a kind of second-orderm-point differential equations system is obtained using the fixed point index theory. As an application, an example to demonstrate our result is given.
