Integral equations theoretical parts and applications have been studied and investigated in previous works. In this work, results on investigations of the uniqueness of the Fredholm-Stiltjes linear integral equations solutions of the third kind were considere…

Gradient-based iterative algorithm is suggested for solving a coupled complex conjugate and transpose matrix equations. Using the hierarchical identification principle and the real representation of a complex matrix, a convergence proof is offered. The necess…

This paper is made up of a desire for me to contribute to this beautiful field of mathematics that I have encountered in recent years. In addition, I would like to mention that I am not aware that there are papers in our Balkans on Lie algebra, although this…

In this paper, we present a unified approach to decomposing a special class of block tridiagonal matrices K ( α , β ) into block diagonal matrices using similarity transformations. The matrices K ( α , β )∈ R pq × pq are of the form K ( α , β = block-tridiag[…

In this paper, we introduce and study some new classes of biconvex functions with respect to an arbitrary function and a bifunction, which are called the higher order strongly biconvex functions. These functions are nonconvex functions and include the biconve…

The undirected power graph P ( Z n ) of a finite group Z n is the graph with vertex set G and two distinct vertices u and v are adjacent if and only if u ≠ v and or . The Wiener index W ( P ( Z n )) of an undirected power graph P ( Z n ) is defined to be sum…

In this study, the SK, SK 1 and SK 2 indices are defined on weighted graphs. Then, the SK, SK 1 and SK 2 indices are defined on interval weighted graphs. Their behaviors are investigated under some graph operations by using these definitions.

We use submultiplicative companion matrix norms to provide new bounds for roots for a given polynomial P ( X ) over the field C[ X ]. From a n × n Fiedler companion matrix C , sparse companion matrices and triangular Hessenberg matrices are introduced. Then,…

We know matrices and their transposes and we also know flip matrices. In my previous paper Matrices-One Review , I introduced transprocal matrix. Flip matrices are transpose of transprocal matrices. Now I would like to introduce water image of four matrices s…

This paper is made out of necessity as a doctoral student taking the exam from Lie groups. Using the literature suggested to me by the professor, I felt the need to, in addition to that literature, and since there was more superficial in that book with some r…

Authors submit their manuscript, metadata, and declarations through the portal. There is no submission fee.
The editorial office screens the manuscript for scope, completeness, and formatting before assigning a handling editor.
At least two independent reviewers evaluate the manuscript under single-blind review. Where revisions are required, authors respond point by point.
On acceptance the article processing charge is invoiced and the CC BY 4.0 copyright handover is signed.
The article is copyedited, typeset, and given a DOI, then publishes open access with a permanent link.
Manuscripts must be original and not under consideration elsewhere. Submit in Microsoft Word or LaTeX with figures at 300 dpi minimum. Structure research articles as Abstract, Introduction, Methods, Results, Discussion, and References.
