| Abstract: | Concave（convex）function is important concepts which is often encountered when discuss the nature of function.Extended the concave and convex of functions of one variable extension to the dual function,obtained some criterions of concave or convex of dual function,gave the methods of seeking for the most value of the dual concave（convex）function. |
| Keywords: | binary function concave or convex projection curve maximum minimum |
