In this work, four finite volume methods have been constructed to solve the
2D convective Cahn–Hilliard equation with specified initial condition and periodic
boundary conditions. We prove existence and uniqueness of ...

This work is concerned with the nonconforming finite approximations for the Stokes and Navier-Stokes equations driven by slip boundary condition of “friction” type. It is well documented that if the velocity is approximated ...

In this paper, we use three existing schemes namely, Upwind Forward Euler, Non-Standard Finite Difference
(NSFD) and Unconditionally Positive Finite Difference (UPFD) schemes to solve two numerical
experiments described ...

Zeilberger’s celebrated algorithm finds pure recurrence relations (w. r. t. a single variable) for hypergeometric
sums automatically. However, in the theory of orthogonal polynomials and special functions,
contiguous ...

The Holland-Batt spline is well known when it comes to plotting spiral separation performance. The
spline, which consists of a linear curve and power curve, has been successfully used to fit test work data
that is presented ...
The total generalised colourings considered in this paper are colourings of the vertices and
of the edges of graphs satisfying the following conditions:
• each set of vertices of the graph which receive the same colour ...
A topic of interest in the finance world is measuring systematic risk.
Accurately measuring the systematic risk component - or Beta - of an asset or
portfolio is important in many financial applications. In this work, ...
In this paper first we define a partial order on a soft set (F, A) and introduce some
related concepts. Then using the concept of a soft mapping introduced by Babitha and Sunil [Comput. Math. Appl., 60 (7) (2010), ...
The science of biology has been transforming dramatically and so the need
for a stronger mathematical background for biology students has increased.
Biological students reaching the senior or post-graduate level often ...

The necessary conditions for existence of a common fixed point of two mappings satisfying
generalized b-order contractive condition in the setting of a partially ordered b-complete b-metric space
are presented. Also, we ...
Abbas, Mujahid; Ciric, Ljubomir; Chandok, Sumit(University of Nis, Serbia, Faculty of Sciences and Mathematics, 2016)
Abbas, Ali and Salvador [Fixed and periodic points of generalized contractions in metric spaces, Fixed Point Theory Appl. 2013, 2013:243] extended the concept of Fcontraction mapping introduced in [21], to two mappings. ...
Some versions of the fundamental principles of the functional analysis in asymmetric
normed spaces – the Open Mapping Theorem, the Closed Graph Theorem and
the Uniform Boundedness Principle – are proved. The proofs are ...
The aim of this paper is to present xed point results of convex contraction, convex contraction of order 2, weakly Zam rescu and Ciric strong almost contraction mappings in the framework of G-metric spaces. Some examples ...
BACKGROUND : Data on human metapneumovirus (HMPV)-associated severe acute respiratory illness (SARI) are limited in settings with high human immunodeficiency virus (HIV) infection prevalence.
OBJECTIVES : To describe ...
This article discusses a computational treatment of the localization
AL of an affine coordinate ring A at a prime ideal L and its
associated graded ring Gra(AL) with the means of standard basis techniques.
Building ...

The spread of a particular trait in a cell population often is modelled by an appropriate system of ordinary differential equations describing how the sizes of subpopulations of the cells with the same genome change in ...
In this paper we study the nonlinear age-structured model of a polycyclic
two-phase population dynamics including delayed effect of
population density growth on the mortality. Both phases are modelled
as a system of ...
