摘要 定义了一类重要的非凸函数——半B-(p,r)-预不变凸函数,它是半预不变凸函数的真推广.首先用例子说明了此类函数的存在性,并说明它是B一不变凸函数、半预不变凸函数和B-(p,r)-预不变凸函数的推广;然后,讨论了半B-(p,r)-预不变凸函数的基本性质与集合刻画,并给出了半B-(p,r)-预不变凸规划问题的非可微最优性条件,其结论具有一般性,推广了涉及不变凸函数、半预不变凸函数和B-(p,r)-预不变凸函数的一些结论. A class of important nonconvex functions-semi-B-(p, r)-preinvex functions is defined, which is true generalization of semipreinvex functions. Firstly, examples are given to show that there exist functions which are semi-B-(p, r)-preinvex functions and illustrate they are generalization of B-invex functions, semi-preinvex functions and B- (p, r) -preinvex functions. Secondly, some basic properties and characterizations of semi-B- (p, r)-preinvex functions are discussed. Lastly, some optimality conditions for nondifferentiable mathematical programming problems are presented under the semi-B-( p, r)-preinvexity. Our results generalize the corresponding ones about invexity, semipreinvexity and B-(p,r)-pre-invexity.
