Abstract: | In this paper, we obtain the sufficient conditions under which there exists the fixed point of sum and product about concave and – convex operators in the positive cone of linear semi-order space, and the iterative procedure and error estimate can be given. The relation between eigenvalue and eigenelement will also be studied in this paper. |
