Twisted immanant and matrices with anticommuting entries

, 2015
This article gives a new matrix function named "twisted immanant," which can be regarded as an analogue of the immanant. This is defined for each self-conjugate partition through a "twisted" analogue of the irreducible character of the symmetric group ...

Small-span Hermitian matrices over quadratic integer rings

, 2013
Building on the classification of all characteristic polynomials of integer symmetric matrices having small span (span less than 4), we obtain a classification of small-span polynomials that are the characteristic polynomial of a Hermitian matrix over ...

Capelli identity on multiparameter quantum linear groups

, 2017
A quantum Capelli identity is given on the multiparameter quantum general linear group based on the $(p_{ij}, u)$-condition. The multiparameter quantum Pfaffian of the $(p_{ij}, u)$-quantum group is also introduced and the transformation under the ...

Quaternionic Hyperbolic Fenchel-Nielsen Coordinates

, 2018
Let $Sp(2,1)$ be the isometry group of the quaternionic hyperbolic plane ${{\bf H}_{\mathbb H}}^2$. An element $g$ in $Sp(2,1)$ is `hyperbolic' if it fixes exactly two points on the boundary of ${{\bf H}_{\mathbb H}}^2$.

A system of dual quaternion matrix equations with its applications

, 2023
We employ the M-P inverses and ranks of quaternion matrices to establish the necessary and sufficient conditions for solving a system of the dual quaternion matrix equations $(AX, XC) = (B, D)$, along with providing an expression for its general solution.

Algebraic technique for mixed least squares and total least squares problem in the reduced biquaternion algebra

, 2023
This paper presents the reduced biquaternion mixed least squares and total least squares (RBMTLS) method for solving an overdetermined system $AX \approx B$ in the reduced biquaternion algebra.

Cokernels of random matrices satisfy the Cohen-Lenstra heuristics [PDF]

, 2013
Let A be an n by n random matrix with iid entries taken from the p-adic integers or Z/NZ. Then under mild non-degeneracy conditions the cokernel of A has a universal probability distribution.

Minor identities for Sklyanin determinants

, 2022
We study the invariant theory for the quantum symmetric spaces of orthogonal and symplectic types using techniques of the R-matrix. We explicitly realize the quantum symmetric spaces as subrings of the quantum coordinate ring $M_q(N)$ and study the ...

Subspace Profiles over Finite Fields and $q$-Whittaker Expansions of Symmetric Functions

, 2023
Bender, Coley, Robbins and Rumsey posed the problem of counting the number of subspaces which have a given profile with respect to a linear endomorphism defined on a finite vector space.

New binary self-dual codes via a generalization of the four circulant construction [PDF]

, 2019
In this work, we generalize the four circulant construction for self-dual codes. By applying the constructions over the alphabets $\mathbb{F}_2$, $\mathbb{F}_2+u\mathbb{F}_2$, $\mathbb{F}_4+u\mathbb{F}_4$, we were able to obtain extremal binary self-dual
