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, 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 ...

In this paper we provide an elementary proof of the existence of canard solutions for a class of singularly
perturbed planar systems in which there occurs a transcritical bifurcation of the quasi steady states. The
proof ...

We consider the stochastic three dimensional magnetohydrodynamic-α model (MHD-α) which arises
in the modeling of turbulent flows of fluids and magnetofluids. We introduce a suitable notion of weak
martingale solution and ...
In this paper we investigate how three well-known modes of convergence for (real-valued) functions are related to one another. In particular, we consider order convergence, pointwise convergence and continuous convergence ...

Homogenization of a stochastic nonlinear reaction–diffusion equation with a large
nonlinear term is considered. Under a general Besicovitch almost periodicity assumption
on the coefficients of the equation we prove that ...

The aim of this paper is to present fuzzy optimal coincidence point results of fuzzy proximal quasi contraction and generalized fuzzy proximal quasi contraction of type1 in the framework of complete non- Archimedean fuzzy ...
We first introduce a new concept of b-dislocated metric space as a generalization of
dislocated metric space and analyze different properties of such spaces.
A fundamental result for the convergence of sequences in ...
