Authors Lecturer, Dept. of Mathematics, Faculty of Education, University of Benghazi, Libya [email protected] Assistant Professor, Dept. of Mathematics, Faculty of Science, University of Benghazi, Libya [email protected] Paper DOI https://doi.org/10.59992/IJSR.2023.v2n12p5 Abstract We consider the nonlinear neutral differential equation: and use the contraction mapping principle to show the asymptotic stability of the… اقرأ المزيد »Asymptotic Stability of Periodic Solutions for a Nonlinear Neutral First-order Differential Equation with Functional Delay

The Egwaider Type-II Distribution

Author Department of Statistics, Faculty of Science, University of Benghazi, Libya [email protected] Paper DOI https://doi.org/10.59992/IJSR.2023.v2n11p6 Abstract The aim of this paper is to illustrate the Egwaider type-II (EGW-II) distribution as a new discrete probability distribution that may will have some practical applications in life. The EGW-II distribution is a discrete… اقرأ المزيد »The Egwaider Type-II Distribution
