| 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.

| Abstract: | 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. |

| Keywords: | quasiconcave functions upper semicontinuity lower semicontinuity |
