Different alleles may be acquired within the inverted segment after the inversion poly morphism is established . 在倒位多形性形成后,在倒位的区段内可能获得不同的等位基因。
On uniqueness of the solution of a morphism equation 态射方程解的惟一性
Existence of morphism on the 的映上的映射的存在性
The aim of this paper is to study the generalized inverse of matrices on rings , the generalized inverse of morphism and partial ordering of matrices 本文研究了环上矩阵的广义逆,范畴中态射的广义逆,并研究矩阵的偏序。
It also discusses some properties of homology regular morphism , and its close relationships to homology monomorphism ( epimorphism ) and homology equivalence 给出了同调正则态射的一些性质,以及它与同调单(满)态和同调等价之间的关系。
We defined the generalized moore - penrose inve rse of morphism , prove it ' s unique when it is existed , and give some its expression in some cases 定义了态射的加权广义逆,证明它的唯一性,在某些情形下给出了存在的充要条件和表达式。
This paper defines homology monomorphism , homology epimorphism , homology regular morphism in the category of topological spaces with point by using homology functor 摘要利用同调函子,在点标拓扑空间范畴中定义了同调单态、同调满态、同调正则态射等概念。
A sequence ( epic , monic ) factorization of morphism is " defined , with the help of the sequence ( epic , monic ) factorization of morphism , some necessary and sufficient conditions for the drazin inverse are obtained 首次定义了态射的满单分解序列,利用其给出了态射的drazin逆存在的充要条件及其表达式。
We research the generalized inverse of morphisms in preadditive category , give the characterization for the moore - penrose and drazin inverse , and obtain the necessary and sufficient conditions for the existence of core - nipotent for morphism 我们考察了预加法范畴中态射的广义逆,利用幂等态射给出了态射广义逆存在的充要条件及其表达式。
Part 2 ( chapter3 ) the moore - penrose inverse and drazin inverse of morphisms with universal - factorzation in category are studied , its existences are characterized , and the expression of the generalized inverse of morphism are establish ( 2 )研究范畴中具有泛分解态射的moore - penrose逆和drazin逆,给出了moore - penrose逆和drazin逆存在的充要条件及其表达式。
In mathematics, a morphism is an abstraction derived from structure-preserving mappings between two mathematical structures. The notion of morphism recurs in much of contemporary mathematics.
