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…

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)…
