quasiconcavity

In this paper, we first introduce some notions about diagonal transfer continuity, diagonal quasiconcavity and FS-convexity, then obtain new existence theorems of Nash equilibria deduced from KKM lemma in non-compact sets.

引进对角转移连续,对角拟凹和FS-凸等概念,然后在非紧的策略集上运用KKM引理得到新的Nash平衡存在性结果。

We conclude that it is quasi-concave.

我们判定它是拟凹的。
