假设T_m(D)是体D上所有上三角m×m矩阵的集合.首先分别给出诱导映射和保幂等性的定义.然后为了刻画T_m(D)的保幂等的诱导映射,提出类序列的概念,同时描述类序列的性质.最后,使用矩阵技术和初等方法,借助于分类讨论得到了T_m(D)的保幂等的诱导映射的一般形式并且给出了某些例子,用以解释某些结果之间的关系. 相似文献

令$\mathcal N$是Banach空间$X$上的套, Alg$\mathcal N$是相应的套代数. 本文证明了, 如果套$\mathcal N$中存在非平凡元$N$在$X$中可补, 且$\dim N\not=1$, 则Alg$\mathcal N$上的每个可加双导子是内导子. 作为此定理的应用, 分别给出了套代数上中心化(交换)映射, 斜中心化导子以及斜交换的广义导子的具体刻画. 相似文献

In this paper,it gives the definition of the category of ■-sets and bi-induced maps whose true value set is a Locale,a complete Heyting algebra.In this category it defines the L_b-monomorphisms and the L_b-epimorphisms.Especially,it gives the definition,the judgmental theorem of L_b-coequalizers.Furthermore,it defines L_b-regular epimorphisms and proves the judgmental theorem.At the end it concludes a result:the category of ■-sets and bi-induced maps is finitely cocomplete. 相似文献

Following a previous work of Tallini (J. Geom.
(1987), 191–199), we investigate the arithmetical properties of a blocking set in a finite projective plane which is met by any line in either 1 or k points, for a fixed number k. The results are then used to give some characterizations of blocking sets of this type which are preserved by a large collineation group of the plane. 相似文献

We present two related categorical constructions. Given a category C, we construct a category C[d], the category of directed systems in C. C embeds into C[d], and if C has enough colimits, then C is monadic over C[d]. Also, if E,M is a factorization structure for C, then C[d] has a related factorization structure Ed Md such that if E consists entirely of monic arrows, then so does Ed and the Ed-quotient poset of an object A is naturally the poset of directed downsets of the E-quotient poset of A. Similarly, if M consists entirely of monicarrows, then so does Md and the Md-subobject poset of an object A is naturally the poset of directed downsets of the M-subobject poset. C[d] has completeness and cocompleteness properties at least as good as those of C, and it is abelian if C is. Dualization gives the other construction: a category C[i], the category of inverse systems in C, into which C also embeds and which satisfies similar properties, except that directed downsets in the E-quotient and M-subobject posets are replaced by directed upsets. 相似文献

首先就双枝模糊集和直觉模糊集的定义和运算进行了比较和讨论,对于它们不同的地方我们通过重新定义直觉模糊集的一些概念使得双枝模糊集能几乎完全地统一到直觉模糊集上来。从而双枝模糊集就可以成为一种特殊的直觉模糊集,所以需要用双枝模糊集解决的问题也就可以用直觉模糊集来解决了。 相似文献

中X是自反Banach空间,K是X的有界、闭、凸子集。研究包含(M)型算子的变分不等式问题:A↑f∈X,求u∈K,使(w-f,v-u)≥0,w∈Tu。其中T是一个有限连续.(M)型、有界集值映射。利用KKM映射和Gwinner定理,我们得到了该变分不等式可解性的结果。最后讨论了这样的变分不等式它的应用。 相似文献
