摘　　要：函数的半连续性与拟凸性的关系已在许多文献中进行了讨论,但函数的半连续性与拟凹性的关系却研究的很少,为此本文在文[1,2]的基础上,在半连续的条件下,给出拟凹函数的两个判别准则。Semi-continuity of functions and quasiconvex have been discussed in many articles, but Semi-continuity of functions and quasiconcave have seldom been studied. So, in this paper we will give two criterions of quasiconcave functions under semicontinuity, according to the article.

关 键 词：拟凹函数 上半连续 下半连续
