Idempotent factorization on some matrices over quadratic integer rings
Peeraphat Gatephan, Kijti Rodtes
In 2020, Cossu and Zanardo raised a conjecture on the idempotent factorization on singular matrices in the form $\begin{pmatrix} p&z\\ \bar{z}&\sfrac{\lVert z\rVert}{p} \end{pmatri…
Some remarks on permanent dominant conjecture
Kijti Rodtes
In this paper we provide an identity between determinant and generalized matrix function. Also, a criterion of positive semi-definite matrices affirming the permanent dominant conj…
Chollet's permanent conjecture for matrices
Kijti Rodtes
In the year 1982, John Chollet conjectured that, for any pair of positive semidefinite matrices , , where is the H…
Matrices over commutative rings as sum of higher powers
Kunlathida Muangma, Kijti Rodtes
On the Waring's problems for matrices over a commutative ring, there are some trace conditions provided for matrices eligibly expressed as a sum of -th powers with $k=2,3,4,5,6,…
Determinants preserving maps on the spaces of symmetric matrices and skew-symmetric matrices
Ratsiri Sanguanwong, Kijti Rodtes
Denote and the set of all symmetric and skew-symmetric matrices over a field , respectively, where and $\lvert \mathbb…
Structured Singular values on some generalized stochastic matrices
Kijti Rodtes, Mutti Ur Rehman Abbasi
In this paper, the exact values of the structured singular values of some generalized stochastic complex matrices is explicit in term of the constant row (column) sum.
Divisibility of LCM matrices by Totally nonnegative GCD matrices
Peeraphat Gatephan, Kijti Rodtes
In this paper, we show that all totally nonnegative GCD matrices are always divisors of the corresponding LCM matrices in the ring . We also introduce \…

In this article, we prove a class of normal dilation matrices affirming the Marcus-de Oliveira conjecture.
Generalized matrix functions on a linear sum of permutation matrices and their cousins
Ratsiri Sanguanwong, Kijti Rodtes
A generalized matrix function is a generalization of determinant and permanent function. In this paper, we introduced the formula for the value of a generalized matrix function of…
The equality of generalized matrix functions on the set of all symmetric matrices
Ratsiri Sanguanwong, Kijti Rodtes
A generalized matrix function is a function constructed by a subgroup of and a complex valued function of . The ma…
On the character tables of symmetric groups
Kamon Kawsathon, Kijti Rodtes
In this paper, some zeros and non-zeros in the character tables of symmetric groups are displayed in the partition forms. In particular, more zeros of self conjugate partitions bes…
Inverse Eigenvalue Problem of Cell Matrices
Sreyaun Khim, Kijti Rodtes
In this paper, we consider the problem of reconstructing an cell matrix constructed from a vector of positive real…
Symmetry classes of tensors and Semi-direct product of finite abelian groups
Kijti Rodtes, Kunlathida Chimla
In the study of symmetry classes of tensors, finding examples of symmetry classes of tensors that possess an o*-basis is of considerable interest. There are only few classes of gro…
On the number of near-vector spaces determined by finite fields
Kijti Rodtes, Wilasinee Chomjun
A slip on a paper concerning near-vector spaces is fixed. New characterization of near-vector spaces determined by finite fields is provided and the number (up to the isomorphism)…
Orthogonal bases of Brauer symmetry classes of tensors for groups having cyclic support on non-linear Brauer characters
Mahdi Hormozi, Kijti Rodtes
