【摘要】 在局部凸拓扑向量空间中确立了新的非空几乎凸几乎下半连续多值映射的逼近选择定理.作为应用,我们还给出了一个平衡存在性定理及不动点定理.这些结果推广和改进了文献中已有的相关结论.更多还原

【Abstract】 Some new approximate theorems for almost lower-semicontinuous multi-valued mapping with almost convex values are establish in locally convex topological vector space. As applications,we also give an equilibrium existence theorem and some fixed point theorems. These results generalize the known conclusions in the literature.更多还原
