Isomorphism. Agroup homomorphism that is bijective;i.e., injective and surjective. Its inverse is also a group homomorphism. In this case, the groups G and H are called isomorphic; they differ only in the notation of their elements and are identical for all practical purposes. What is homomo...
Group theory 算就是指连接变换:9192表示先旋转g:,然后接着进行旋转91。单位元素即指旋转了零角度,也就是等于没有转动。而一个元素的逆元素是绕同一轴在相反指向下旋转相同的角。容易证明,若g;是绕铅直轴旋转90“,而g:是绕某水平轴旋转90“,则9192并g店」,因而群是非交换的。 这三个群的例子都是具有无穷...
We extend well-known results in group theory to gyrogroups, especially the isomorphism theorems. We prove that an arbitrary gyrogroup $G$ induces the gyrog... T Suksumran,K Wiboonton - 《Eprint Arxiv》 被引量: 19发表: 2014年 On Lusztig's Isomorphism Theorems for Hecke Algebras and Repr...

The homomorphism and isomorphism theorems traditionally taught to students in a group theory or linear algebra lecture are by no means theorems of group theory. They are for a long time seen as general concepts of universal algebra. This article goes even further and identifies them as relational...
Preservation of this topographic orderliness by an interpolation method so that "if point A is higher than point B in the terrain, the interpolated elevation of A remains higher" is important to assure the practical value of the resultant DEM. Based on the concepts in group theory, this paper...
Isomorphism, in brief , means two graphs possess identical topological structures. 所谓图的同构,就是指两个图的拓扑结构完全相同. 互联网 On theIsomorphismof Ba Jin's " Family Story " and " Group Story " 论巴金 “ 家庭故事 ”与“ 团体故事 ” 的同构性. ...
