在這篇論文中,我們首先在一完備度量空間之有界凸子集上探討一個收縮函數的定點定理。其次,我們在這一條件下得到一些同質點定理,匹配定理及變分不等式。
In this paper, we first establish the fixed-point theorem for k-set contraction map on a bounded subadmissible subset of a complete metric space, which not need a compact map. Next, we get some coincidence theorems, matching theorems and variational inequalities on this class.
