  • 本論文,第一部份,我們在Q(X,Y)集族上建立k-集收縮映射之固定點定理。第二部份,我們把在凸集上KKM性質推廣至近似凸集上KKM *性質,接著我們建立這個集族的固定點定理。


    In this paper, the first part, we establish a fixed point theorem for a k-set contraction map on the class Q(X,Y) , ( see [ 1 ] ) . The second part, we generalize the KKM property on a convex set [ 2 ] to he KKM* property on a nearly-convex set, and then we establish a fixed point theorem for this class.
