In this paper we establish a generalization of the right Fejer´ inequality for general Lebesgue integral on measurable spaces as well as a positive lower bound and some upper bounds for the differen ... Read More
In harmonic analysis, wavelets are useful and important tools for analyzing problems and equations. As far as we know, the wavelet applications for solving differential equations are limited to solv ... Read More
In this paper we propose a nonstandard finite difference scheme for an epidemic model which considers the effect of media coverage on the spread of some infectious diseases. We show that this scheme ... Read More
For a graph G = (VG, EG), consider a mapping h : EG → {0, 1, 2, . . . , k − 1}, 2 ≤ k ≤ |EG| which induces a mapping h ∗ : VG → {0, 1, 2, . . . , k − 1} such that h ∗ (v) = Qn i=1 h(ei)( mod k) ... Read More
Hepatitis B is a contagious liver infection caused by hepatitis B virus and is a worldwide public health problem. According to WHO about 350 million people are suffering from this chronic disease. T ... Read More
We consider a system of a pair of quasi one dimensional BoseEinstein condensates which are coupled with each other. The waveguides of the two condensates are assumed to be parallel. The system can be ... Read More
We consider a financial market where there are brusque variations in the price of an asset and an European option on this asset. In this setup the value as well as the hedging process functions are e ... Read More
This paper deals with a new application of Bernstein polynomials to find approximate solution of linear Volterra Integro-differential equation of a special kind. For this purpose, we first need to co ... Read More
Kidney Dialysis is considered as one of the world’s major health problems. Level of occurrence of this illness is high and every year increases by %8. Kidney Dialysis refers to temporary or permanen ... Read More
. In this paper, we establish connections between the Hyers– Ulam stability of the first order linear dynamic system and its dichotomy. The main tool for proving our results is the spectral decompos ... Read More
In this paper, we first utilize the least squares strategy for the (2n) 2 -observations to fit bivariate cubic polynomial for n ≥ 2. At that point the (2n) 2 -point approximating subdivision sch ... Read More
This article presents some starting solutions corresponding to unsteady rotational flow of a second grade fluid with the non-integer Caputo time fractional derivatives through an infinite long cylind ... Read More
In 1931, the young Austrian mathematician that a formal mathematical system is either incomplete or inconsistent. To put it in another words that there statements in mathematics which are un decidabl ... Read More
In this paper we give the refinement of Jensen-Mercer’s and power mean inequalities for operators. We launch the corresponding mixed symmetric means for strictly positive operators defined on Hilber ... Read More
This article leads to free convection problem of magnetohydrodynamic second grade fluid with porous medium using recently defined Caputo-Fabrizoi fractional derivatives. Analytical expressions for te ... Read More
In this article, the main properties of a somewhere dense set [13] on topological spaces are studied and then it is used to generalize the notions of interior, closure and boundary operators. The cl ... Read More
Global Optimization has become an important branch of mathematical analysis and numerical analysis in the recent years. Practical example of the optimization problems including the design and optimiza ... Read More
In the study of ecological sciences predator-prey models are very beneficial and they are frequently used because dynamics of animal populations can easily be observed and researchers can also predi ... Read More
In this paper, a modified factor-type estimator under two-phase sampling has been suggested. The suggested estimator is obtained by incorporating information like coefficient of variation, kurtosis, ... Read More
