EXISTENCE OF POSITIVE FIXED POINTS FOR SEMIDIFFERENTIABLE SEMICOMPACT 1-SET-CONTRACTIONS

This paper obtains some fixed point theorems of semidifferentiable semmicompacl l-set-contraction maps, which extend some known results in [1, 2, 4, 5, 7].     

Random attractors for asymptotically upper semicompact multivalue random semiflows

The present paper studied the dynamics of some multivalued random semi- flow.The corresponding concept of random attractor for this case was introduced to study asymptotic behavior.The existence of random attractor of multivalued random semiflow was proved under the assumption of pullback asymptotically upper semicompact,and this random attractor is random compact and invariant.Furthermore,if the system has ergodicity,then this random attractor is the limit set of a deterministic bounded set.     

半可微半紧1-集压缩映象的正不动点的存在性

本文得到一些半可微半紧1-集压缩映象的不动点定理.这些结果是[1,2,4,5,7]中某些已知结果的推广.     

L-拓扑空间的局部半紧性

定义了L-拓扑空间的局部半紧性,证明了这种局部半紧性是L-好的推广,是半闭可遗传的,在irresolute、开的、满的L值Zadeh型函数下保持不变.     

渐近上半紧的多值随机半流的随机吸引子

该文研究多值随机半流的随机吸引子的存在性．首先证明在拉回渐近上半紧及吸收的条件下,关于极限集的一个抽象结果,然后证明了随机的吸引子的存在性．     

非锥序的有效点的存在性与外在稳定性

本文讨论了非锥序的有效点的存在性与外在稳定性，并且各给出了一个充要条件，在此基础上，对序－半紧集的有效点的存在性与外在稳定性给出了一些充分条件，最后，在决策空间中给出了相应的结果。
