On S-2-absorbing submodules and vn-regular modules

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020
Let R be a commutative ring and M an R-module. In this article, we introduce the concept of S-2-absorbing submodule. Suppose that S ⊆ R is a multiplicatively closed subset of R.

ON A POWER OF THE COMPANION MATRIX

Süleyman Demirel Üniversitesi Fen-Edebiyat Fakültesi Fen Dergisi, 2009
: In this study, we have given some results which have computed power of the companion matrix and the algorithms which are based on these results. So we also have given numerical examples using these algorithms.

Further results on permanents of Laplacian matrices of trees

Open Mathematics
The research on the permanents of graph matrices is one of the contemporary research topic in algebraic combinatorics. Brualdi and Goldwasser characterized the upper and lower bounds of permanents of Laplacian matrices of trees.

On an uncertainty principle for small index subgroups of finite fields

Open Mathematics
In this article, we continue the study of the nonvanishing minors property initiated by Garcia, Karaali, and Katz, for the compressed Fourier matrix attached to a subgroup HH of the multiplicative group of a finite field Fq{{\mathbb{F}}}_{q} and a ...

Convergence analysis of non-matching finite elements for a linear monotone additive Schwarz scheme for semi-linear elliptic problems

Nonlinear Engineering
In this article, we are interested in the standard finite element approximation method of linear additive Schwarz iterations for a class of semi-linear elliptic problems, for two subdomains, in the context of non-matching grids.
