半E-预不变凸模糊数值函数的次微分
The Subdifferential of Semi-E-Preinvex Fuzzy-Valued Functions

基于模糊数空间的一种新序关系,引入了新的半E-预不变凸模糊数值函数的次微分的定义,并利用次微分映射的最大循环单调性刻画了半E-预不变模糊数值函数的次微分.
Based on a new concept of ordering,the definition of the subdifferential of semi-E-preinvex fuzzy-valued function is given.Then the characterization of the subdifferential by the maximum cycle monotonicity is discussed
