摘要:
利用集值映象不动点存在性方法讨论当非线性函数g:[b,b+L]×Ω→R满足某些条件时,微分方程x′(t)+g(t,x(t))=0的解的存在性及解的性质等问题.%In this paper, by using a fixed point method of set-valued mapping, we discuss the differential equation x′ (t)+g(t,x(t)) = 0. The existence of solutions and their properties of this equation is obtained if the function g. [b,b+L] ×Ω →R satisfy certain conditions.

摘要:
在文献[5-10]中Isac等人发现当多值互补问题无解时,与之相联系的映象一定存在一个序列满足一组条件,Isac等人称这个序列为例外簇,另一方面,当多值互补问题有解时,与之相联系的映象一定不存在例外簇。该文证明了几类互补理论所涉及的非线性映象没有例外簇元,并得出与之相联系的集值互补问题(MCP)是可解的。%Some mathematicians, such as lsac, found out that, in literature 5 - 10, there exists a certain group of conditions for certain mappings relating to no solution to multi - valued complementary problems, it is called exceptional family; and also, if there are solutions, there is no this kind of family. This paper is to prove that the corresponding complementary problems are solvable by identifying some classes of nonlinear tunctions without exceptional families of elements

摘要:
The auxiliary principle technique is extended to investigate a class of generalized set-valued strongly nonlinear variational-like inequalities. Firstly, the existence of solutions to the auxiliary problems for this class of mixed variational-like inequalities is shown by virtue of Ky Fan's lemma. Secondly, the iterative algorithm for solving this class of mixed variationallike inequalities is given by using this existence result. Finally, not only the existence of solutions of this class of mixed variational-like inequalities is shown, but also the convergence of iterative sequences generated by the algorithm is proven.%本文延拓辅助原理的技巧,来研究一类广义集值强非线性混合似变分不等式.首先,利用KyFan引理,证明了这类混合似变分不等式的辅助问题解的存在性.其次,利用该存在性结果,给出了解这类混合似变分不等式的迭代算法.最后,既证明了这类混合似变分不等式解的存在性,又证明了由算法生成的迭代序列的收敛性.

摘要:
Ball intersection valued nonexpansive multifunctions with ranges in hyperconvex space is studied. It is showed that such multifuntion A on a subspace of a metric space M has an nonexpansive extension A on M with same form of ranges and for every nonexpansive point valued selection T of A there is a nonexpansive point valued selection T of A such that T is the nonexpansive extension of T. Two equivalent conditions about hyperconvexity are also obtained.%作者研究了超凸空间中球交为值的非扩张集值映象,指出在度量空间M的子空间上的这样的映象A必有在M上的具球交值的非扩张延拓(A),且对A的任何非扩张单值选择T及A的任何在M上具球交值的非扩张延拓(A),(A)必有非扩张单值选择T,使T为T在M上的非扩张延拓,并获得了两个关于超凸性的等价条件.
