摘要: 研究了锥意义下的半预不变凸性的新性质.首先,对彭再云等的文献(彭再云, 李科科, 唐平, 黄应全.向量值D-半预不变真拟凸映射的判定与性质[J].重庆师范大学学报(自然科学版), 2014,31( 5 ): 18-25.)中的例4进行了修正,使其满足条件E.然后,给出了条件E1的一个重要性质,并在此基础上结合稠密性结果,分别利用D-半严格半预不变真拟凸性和D-严格半预不变真拟凸性建立了D-半预不变凸性的刻画.最后利用D-半预不变真拟凸性给出了D-预不变凸性的刻画.

Abstract: Some new properties of semi-preinvexity in the sense of cones were studied. Firstly, Example 4 in the paper of PENG Zai-yun, etc.(PENG Zai-yun, LI Ke-ke, TANG Ping, HUANG Ying-quan. Characterizations and criterions of D-semiprequasi-invex mappings[J].Journal of Chongqing Normal University(Natural Science),2014,31( 5 ):18-25.) was modified to satisfy condition E. Then, an important property of condition E1 was obtained. Based on this property and the results of density, two characterizations of D-semi-preinvexity were established by means of D-semi-strict semi-prequasiinvexity and D-strict semi-prequasiinvexity, respectivley. In the end,D-semi-preinvexity was characterized with D-semi-prequasiinvexity. -
