摘　　要：对于拟凹函数的一些性质,文[1~3]已经给予了研究,文[4]也给出了拟凹函数的两个判别准则.本文在此基础上,在半连续条件下,给出了强拟凹函数的两个充要条件.Some characteristics properties of quasiconcave function were studied by article,two criterions of quasiconcave functions under semicontinuity were given in article [4].According to these,two necessary and sufficient condition of strong quasiconcave function have been given in the paper.

关 键 词：上半连续函数 下半连续函数 稠密性 强拟凹函数
