Structure of coincidence isometry groups

Autor: Deng Guixin, Zhao Jinxing

Publikováno v: Open Mathematics, Vol 19, Iss 1, Pp 1517-1527 (2021)

Let LL be a lattice of rank nn in an nn-dimensional Euclidean space. We show that the coincidence isometry group of LL is generated by coincidence reflections if and only if LL contains an orthogonal subset of order nn.

Remark on subgroup intersection graph of finite abelian groups

Autor: Zhao Jinxing, Deng Guixin

Publikováno v: Open Mathematics, Vol 18, Iss 1, Pp 1025-1029 (2020)

Let G be a finite group. The subgroup intersection graph Γ(G)\text{Γ}(G) of G is a graph whose vertices are non-identity elements of G and two distinct vertices x and y are adjacent if and only if |〈x〉∩〈y〉|>1|\langle x\rangle \cap \langle

Dynamics of Endomorphism of Finite Abelian Groups

Autor: Zhao Jinxing, Nan Jizhu

Publikováno v: Discrete Dynamics in Nature and Society, Vol 2017 (2017)

We study the dynamics of endomorphisms on a finite abelian group. We obtain the automorphism group for these dynamical systems. We also give criteria and algorithms to determine whether it is a fixed point system.
