| Abstract: |
| In this paper, we study some nonlinear problems of dual cone mapping. By using topological degree theory and partial order methods, we get the results of the acute angle principle, Debrunner-Flor inequality and fixed point theorem for dual cone mapping. Some results in the document are improved and extended. |
| Key words: dual cone mapping acute angle principle Debrunner-Flor inequality fixed point |
