在本文中,证明了F是(严格)伪凸模糊映射当且仅当▽F是(严格)伪单调的,F是拟凸模糊映射当且仅当▽F是拟单调的等几个广义凸模糊映射的等价条件。在模糊数学规划中,这些结果在检验模糊映射的广义凸性以及刻画其解集时,将会产生非常重要的作用。
In this paper, we obtain that a fuzzy mapping F is (strictly) pseudoconvex if and only if VF is (strictly) pseudo- monotone, and a differenitiable fuzzy mapping F is quasiconvex if and only if VF is quasimonotone. These results will be useful in checking the generalized convexity of the differenitiable fuzzy mapping and presenting some characterizations of solutions for fuzzy mathematical programming.
