摘要
通过引入强道路转移下半连续的概念,得到了L-凸空间中的广义Ky-Fan不等式,从而得到了L-凸空间中的广义Fan-Browder不动点定理、截口定理和鞍点定理.
By the strongly path transfer lower semicontinuous,the generalized Ky-Fan InequaLity in L-convex spaces is obtained,then Fan-Browder fixed point theorem,section theorem,maximal elements theorem and saddle-point theorem is derived.
