On finite totally k-closed groups
Jiawei He, Xiaogang Li
Let be a finite group acting faithfully on a finite set . For a positive integer , acts naturally on the Catesian product . In this paper,…
The endomorphism rings of permutation modules of -transitive permutation groups
Jiawei He, Xiaogang Li
Recent classification of -transitive permutation groups leaves us with six families of groups which are -transitive, or Frobenius, or one-dimensional affine, or the…
Schur rings over Free Abelian Group of Rank Two
Gang Chen, Jiawei He, Zhiman Wu
Schur rings are a type of subrings of group rings afforded by a partition of the underlined group. In this paper, Schur rings over free abelian group of rank two are classified und…
Construction of finite differentiable quasi-periodic Schrödinger operators with cantor spectrum
Jiawei He, Hongyu Cheng
In this paper, we present an approach for explicitly constructing quasi-periodic Schrödinger operators with Cantor spectrum with potential. Additionally, we provide polynomia…
