The Depth Distribution of Constacyclic Codes Over
IEEE Access, 2018 The depth distribution of a linear code was put forward by Etzion as a new characterization for linear codes. The previously known results pay close attention to the depth distribution of the linear codes over chain rings.

Skew Constacyclic Codes over Finite Fields and Finite Chain Rings [PDF]
Mathematical Problems in Engineering, 2016 This paper overviews the study of skewΘ-λ-constacyclic codes over finite fields and finite commutative chain rings. The structure of skewΘ-λ-constacyclic codes and their duals are provided. Among other results, we also consider the Euclidean and Hermitian dual codes of skewΘ-cyclic and skewΘ-negacyclic codes over finite chain rings in general and ...

IEEE Access, 2020 Let p ≠ 3 be any prime. The structures of all λ-constacyclic codes of length 3ps over the finite commutative chain ring Fpm + uFpm (u2 = 0) are established in the term of their generator polynomials.

A Single Oscillator-Excited Piezoelectric Actuator with Internal Contact Teeth
Micromachines, 2023 The tail rotor of a helicopter, a crucial component, traditionally relies on a complex drive mode involving reducers and transmission gears. This conventional setup, with its lengthy transmission chain and numerous components, hinders miniaturization ...

Galois correspondence on linear codes over finite chain rings [PDF]
Discrete Mathematics, 2020 Given $\texttt{S}|\texttt{R}$ a finite Galois extension of finite chain rings and $\mathcal{B}$ an $\texttt{S}$-linear code we define two Galois operators, the closure operator and the interior operator. We proof that a linear code is Galois invariant if and only if the row standard form of its generator matrix has all entries in the fixed ring by the ...

Vanishing Wilson ratio as the hallmark of quantum spin-liquid models
Physical Review Research, 2020 We present numerical results for finite-temperature T>0 thermodynamic quantities, entropy s(T), uniform susceptibility χ_{0}(T), and the Wilson ratio R(T), for several isotropic S=1/2 extended Heisenberg models, which are prototype models for planar ...

The weight distribution of codes over finite chain rings
Linear Algebra and its Applications, 2023 In this work, we determine new linear equations for the weight distribution of linear codes over finite chain rings. The identities are determined by counting the number of some special submatrices of the parity-check matrix of the code. Thanks to these relations we are able to compute the full weight distribution of codes with small Singleton defects,

Zassenhaus conjecture for central extensions of S5 [PDF]
, 2008 We confirm a conjecture of Zassenhaus about rational conjugacy of torsion units in integral group rings for a covering group of the symmetric group S5 and for the general linear group GLð2; 5Þ. The first result, together with others from the literature,
