Skew-product groups of finite abelian -groups
Jiawei He
A skew-morphism of a finite group is a permutation of fixing the identity element such that there exists a function satisfying $σ(xy)=σ(x)σ^{π(…
Cantor Spectrum via a Reducibility-Duality Bridge for the Mosaic Almost Mathieu Operator
Jiawei He, Yuan Shan, Yongjian Wang
We study the mosaic Almost Mathieu operator, a quasiperiodic model that naturally admits a singular strip-Jacobi representation. By establishing a duality framework and extending t…
Long-time dynamics for time-nonlocal generalized Rayleigh-Stokes equations
Li Peng, Lin Deng, Jia Wei He
In this paper, we consider an autonomous semi-dynamical system driven by semilinear time-nonlocal evolution equations, these type equations are used to describe the Rayleigh-Stokes…
Non-Hermitian Anomalous Scaling Engineering
Shulin Wang, Jiawei He, Zhiyuan Yang +2
Non-Hermitian systems exhibit anomalous scaling, a striking departure from conventional bulk laws, rooted in the non-Hermitian skin effect (NHSE). Here, we experimentally uncover t…
Admissibility approach to nonuniform exponential dichotomies roughness with nonlocal perturbations
Jiawei He, Jianhua Huang
Nonuniform exponential dichotomy serves as an important characteristic of nonuniform hyperbolicity, while admissibility of function classes is often used to characterize nonuniform…
Permutation groups and symmetric Hecke algebras
Jiawei He, Xiaogang Li
The endomorphism algebras of the permutation modules for transitive permutation groups, known as Hecke algebras, are fundamental objects in representation theory. While group algeb…
Approximation for stochastic time-space fractional cable equations driven by rough noise
Jiawei He, Jianhua Huang, Fang Su +1
The time-space fractional cable equation arises from extending the generalized fractional Ohm's law to model anomalous diffusion processes. In this paper, we develop and analyze a…
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…
Schur rings over infinite dihedral group
Gang Chen, Jiawei He, Zhiman Wu
Schur rings over the infinite dihedral group are studied according to properties of Schur rings over infinite groups and the classification of Sch…
Arithmetic Phase Transitions For Mosaic Maryland Model
Jiawei He, Xu Xia
We give a precise description of spectral types of the Mosaic Maryland model with any irrational frequency, which provides a quasi-periodic unbounded model with non-monotone potent…
Schur Rings over Z \times Z_3
Gang Chen, Jiawei He
For the direct product $\cZ\times \cZ_3$ of infinite cyclic group $\cZ$ and a cyclic group $\cZ_3$ of order , the schur rings over it are classified. In particular, all the schu…
A characterization of exceptional pseudocyclic association schemes by multidimensional intersection numbers
Gang Chen, Jiawei He, Ilia Ponomarenko +1
Recent classification of -transitive permutation groups leaves us with three infinite families of groups which are neither -transitive, nor Frobenius, nor one-dimen…
