General Letters in Mathematics (GLM) is a peer-reviewed, open access journal dedicated to publishing original research papers across all areas of mathematics. Published quarterly by Refaad, GLM aims to provide a prestigious platform for disseminating significant mathematical findings. While the journal is committed to highlighting contributions from mathematicians in the Middle East and Arab countries, it also welcomes high-quality submissions from researchers worldwide.

Median time to first decisionBootstrap Procedure for Correlation Model of Random Design Under Strong Dependence
This paper investigates the validity of a bootstrap least square estimate of a polynomial correlation model whose error terms are an autoregressive fractionally integrated moving average ARFIMA (p,d,q) strongly dependent time series. For an (r + 1)*1 vector B of unknown parameters, ^Ba an ...
Irrational Outputs from Rational Inputs in Theta-3 Functions Using Dirichlet’s Theorem
Theta Functions are not an easy subject of mathematics because new researches about this wide topic are still being published regularly. The findings about Theta Functions lead directly to many applications in different fields of applied mathematics and help also to develop old interesting mathematical ...
Semi-symmetric types on hyperbolic Kenmotsu manifolds
In this paper, we give some necessary conditions for an hyperbolic Kenmotsu manifolds M satisfying semi-symmetric, Ricci semi-symmetric, Weyl semi-symmetric and Einstein semi-symmetric. Next, we study the notion of n-Ricci soliton in context of hyperbolic Kenmotsu 3-manifolds M3 and we construct an example ...
A new Approach to Hyper Dual Split Quaternions with Different Polar Representation
Hamilton first introduced quaternions in 1843 as a way to represent rotations in three dimensional space, and since then, they have become the important tool in many fields. One advantage of quaternions over other methods of representing rotations is their ability to avoid the problem of gimbal lock, ...
