In the paper we present a survey of recent results obtained by the author that concern discrete fragmentation–coagulation models with growth. Models like that are particularly important in mathematical biology and ecology ...

Ebola virus disease (EVD) is a zoonotic disease (i.e. disease that is spread
from animals to people). Therefore human beings can be infected through direct contact
with an infected animal (fruit-eating bat or great ape). ...
In this article, the effects of time delay and carrying capacity in the dynamics of viral phytoplankton and consistence numerics are studied. Basic properties and stabilities of equilibria are rigorously analyzed and ...

We introduce a hybrid proximal point algorithm and establish its strong convergence to a common solution of a proximal point of a lower semi-continuous mapping and a fixed point of a demicontractive mapping in the framework ...
Oil palm production is of economical importance in several southern countries. The increasing demand of oil palm put a lot of pressure in several places where the rain forest and thus the tropical diversity are in danger ...
Syphilis, a major sexually transmitted disease, continues to pose major public health burden in both underdeveloped and developed nations of the world. This study presents a new 2‐group sex‐structured model for assessing ...
The realification of the (2n + 1)-dimensional complex Heisenberg Lie algebra is a (4n + 2) -dimensional real nilpotent Lie algebra with a 2-dimensional commutator ideal coinciding with the centre, and admitting the compact ...

In this research we describe how forward-looking information on the statistical properties of an asset
can be extracted directly from options market data and demonstrate how this can be practically applied
to portfolio ...

A copula is a function which joins (or ‘couples’) a bivariate distribution function to its
marginal (one-dimensional) distribution functions. In this paper, we obtain
Chebyshev type inequalities by utilising copulas.
Mathematical models for chemically reacting systems have high degrees of freedom (very large) and are computationally expensive to analyse. In this discussion, we present and analyse a model reduction method that is based ...
Berge, Tsanou; Bowong, Samuel; Lubuma, Jean M.-S.; Manyombe, M.L.M. (Martin Luther Mann)(American Institute of Mathematical Sciences, 2018-02)
We propose a new deterministic mathematical model for the transmission dynamics of Ebola Virus Disease (EVD) in a complex Ebola virus life ecology. Our model captures as much as possible the features and patterns of the ...
We investigate the isometry groups of the left-invariant Rieman-
nian and sub-Riemannian structures on simply connected three-dimensional
Lie groups. More speci cally, we determine the isometry group for each nor-
malized ...
Diseases, in particular, vector-borne diseases are very important issues in crop protection. However, despite their impact on food safety, very few mathematical models have been developed in order to improve control ...

In this article, we derive error estimates for the semi-discrete and fully discrete Galerkin approximations of a general linear second-order hyperbolic partial differential equation with general damping (which includes ...
The aim of this paper is to introduce a class of generalized Suzuki type (α∗,ψφ)-contractive multivalued operators and to prove the existence of fixed point and common fixed point of such operators in the setup of b-metric ...
Leyew, Bahru Tsegaye; Mujahid, Abbas(University Politehnica of Bucharest, 2017)
In this paper, we introduce the concept of a generalized-Suzuki-Geraghty type
contraction mapping and obtain fixed point results in the framework of an f-orbitally
complete b-metric space. The results proved herein ...
Abbas, Mujahid; Rakocevic, Vladimir; Leyew, Bahru Tsegaye(University of Nis, Serbia, Faculty of Sciences and Mathematics, 2017)
In this paper, the concept of (α − ψ)-generalized rational contraction multivalued operator is introduced and then the existence of common fixed points of such mapping in complete dislocated quasi b-metric spaces is obtained. ...
