查询词典 matrix semigroup

From [1], Every transition function is a positive strongly continuous semigroup of contractions on l\, but it isnt a strongly continuous semigroup on l_∞- In fact, the sufficient and necessary condition for a transition function to be a strongly continuous semigroup on l_∞ is that the q—matrix Q is an uniformly bounded q—matrix on l_∞- This is the trivial case.

由Anderson[1]知道转移函数P是l_1空间上正的强连续压缩半群，但P一般来说不是l_∞空间上的强连续半群，而P是l_∞上强连续半群的充要条件是q—矩阵Q是l_∞。

In chapter 2, we prove that an abundant semigroup satisfying the regularity is a locally E-solid semigroup if and only if it is an E-local isomorphic image of some abundant Rees matrix semigroup AM over an E-solid abundant semigroup with entries of the sandwich matrix P being regular elements of T.

第二章，我们证明了满足正则性条件的富足半群是局部E-solid(quasi-adequate，R~*-unipotent)半群当且仅当它是某个富足Rees矩阵半群RM的E-local同构像，其中sandwich矩阵的P元素是T中的正则元。

Lastly , from a primitive rpp semigroup with zero , we built up a type A blocked Rees matrix semigroup and showed a semigroup S is a primitive rpp semigroup if and only if S is isomorphic toa type A blocked Rees matrix semigroup.

该结果的一个特例就是可消幺半群上的Rees矩阵半群。

By the definition of Green-relation and the analogue of generalized Greens lemma, this paper first studied some properties of H-class、 D--class of rpp semigroups, then by left S-system 、-bisystem and tensor product, we described a blocked Rees matrix semigroup. Especially, the paper studied primitive rpp semigroups .

本文利用在rpp半群上定义的广义Green~(l-关系及相应的广义Green定理，首先研究了rpp半群H~(l-类、D~(l-类的若干基本性质，然后以左S-系、-双系和张量积作为工具，刻画了块Rees矩阵半群结构，最后从带零的本原rpp半群出发，构造出A型块Rees矩阵半群，并证明了一个半群S为本原rpp半群，当且仅当S同构于一个A型块Rees矩阵半群。

Eigenvalue matrix for resolving sparse polynomial equations is constructed by deploying well arranged basis in semigroup algebra k.

本文利用半群代数k中良序基，构造了求稀疏多项式方程组解的特征值矩阵，并给出了可以构造方阵的条件。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
