摘要
对模糊映射的LgH-方向可微性问题进行了研究,给出了模糊映射的LgH-方向可微的概念及性质,同时讨论了模糊映射的LgH-方向可微性与gH-方向可微性之间的关系,得到了LgH-方向可微的几个必要条件,并证明了模糊映射的LgH-导数和LgH-偏导数均为沿特殊方向的LgH-方向导数.
The LgH-directional differentiability problems of fuzzy mapping were studied.The concepts and prop⁃erties of LgH-directional differentiability of fuzzy mapping were given,and the relationship between LgH-direc⁃tional differentiability and gH-directional differentiability of fuzzy mapping was discussed.At the same time,sev⁃eral necessary conditions of LgH-directional differentiability were obtained,and it is proved that the LgH-deriva⁃tive and LgH-partial derivative of fuzzy mapping are both LgH-directional derivatives along with the special di⁃rection.
