主要利用局部凸空间中Fan—Kakutani不动点定理,将参考文献[1]中得到的局部凸空间中集值映射的极小不动点定理进行推广,把原定理中的半范数条件减弱为次可加泛函,得到具局部凸空间中集值映射的一个极小不动点定理.
In this paper, by Fan - kakutani fixed point theorem, we generalized the extreme minimum fixed point theorem for set - valued mapping in the local convex space in reference [ 1 ]. We use sub - additive functional instead of semi - norm, proved a extreme minimum fixed point theorem for set - valued mapping in the local convex space.
