摘要
提出了一类新的向量值映射—D-半预不变真拟凸映射,它是D-预不变真拟凸映射与D-半预不变凸映射的真推广。首先,给出例子说明半不变凸集、D-半预不变真拟凸映射的存在性;然后,给出了相关集合的稠密性结果以及在下D-半连续条件下D-半预不变真拟凸映射的判定,并建立了D-半预不变真拟凸映射与D-严格/半严格半预不变真拟凸映射间的关系;最后,讨论了D-半严格半预不变真拟凸映射在向量优化问题中的一个应用,并举例验证了所得结论的正确性。
A class of new vector valued generalized convex mappings--D-semiprequsai-invex mappings, which is a true generalization of D-prequasi-invex mapping[14] and D-semipre-invex mapping[15], is given in this paper. Firstly, examples are given to show the existence of semi-invex sets and D-semiprequasi-invex mappings. Secondly, the density result of corresponding set and a criterion of D-semiprequasi-invexity under the condition of D-lower semicontinuous are given. Then, the relationships among D-semiprequasi- invexity, D-strictly semiprequasi-invexity and D-semistrictly semiprequasi-invexity are discussed; Finally, an important application of D-semiprequasi-invexity in vector optimization problem is obtained, and some examples are given to illustrate the results.
