1.
In this paper, we introduce the concept of closed function, obtain two sufficient and necessary conditions that the closed function is a quasiconcave function, and study the relation between quasiconcave function, strictly quasiconcave function and strongly quasiconcave function.
研究了一类函数成为拟凹函数的充分必要条件,讨论了拟凹函数与严格拟凹函数和强拟凹函数的关系。
6) strict quasi-convexity
严格拟凸性
