Approximation by integral functions of finite degree in variable exponent lebesgue spaces on the real axis
(Scientific Technical Research Council Turkey-Tubitak, 2018)We obtain several inequalities of approximation by integral functions of finite degree in generalized Lebesgue spaces with variable exponent defined on the real axis. Among them are direct, inverse, and simultaneous estimates ... -
Some fixed-point results on parametric N-b -metric spaces
(Korean Mathematical Soc, 2018)Our aim is to introduce the notion of a parametric N-b-metric and study some basic properties of parametric N-b-metric spaces. We give some fixed-point results on a complete parametric N-b-metric space. Some illustrative ... -

Approximation problems in the lebesgue spaces with variable exponent
(Academic Press Inc Elsevier Science, 2018)In the variable exponent Lebesgue space, the r-th modulus of smoothness (r = 1,2, ... ) is defined and in this term, the direct and inverse theorems of approximation theory are proved. Moreover, the constructive characterization ... -
European vanilla option pricing model of fractional order without singular kernel
(MDPI, 2018)Recently, fractional differential equations (FDEs) have attracted much more attention in modeling real-life problems. Since most FDEs do not have exact solutions, numerical solution methods are used commonly. Therefore, ... -
