Pre-Schur convex functions and some integral inequalities on domains from plane

Acta Universitatis Sapientiae: Mathematica, 2023
In this paper we introduce the concept of pre-Schur convex functions defined on general domains from plane. Then, by making use of Green’s identity for double integrals, we establish some integral inequalities for this class of functions that naturally ...

Bounds for modified Struve functions of the first kind and their ratios [PDF]

, 2018
We obtain a simple two-sided inequality for the ratio $\mathbf{L}_\nu(x)/\mathbf{L}_{\nu-1}(x)$ in terms of the ratio $I_\nu(x)/I_{\nu-1}(x)$, where $\mathbf{L}_\nu(x)$ is the modified Struve function of the first kind and $I_\nu(x)$ is the modified ...

Finite-Time Mixed H_∞/Passivity for Neural Networks With Mixed Interval Time-Varying Delays Using the Multiple Integral Lyapunov-Krasovskii Functional

IEEE Access, 2021
In this article, we consider the finite-time mixed $H_{\infty }$ /passivity, finite-time stability, and finite-time boundedness for generalized neural networks with interval distributed and discrete time-varying delays.

Double Integral Operators Concerning Starlike of Order β

International Journal of Differential Equations, 2009
Double integral operators which were considered by S. S. Miller and P. T. Mocanu (Integral Transform. Spec. Funct. 19(2008), 591–597) are discussed. In order to show the analytic function f(z) is starlike of order β in the open unit disk 𝕌, the ...

Integral inequalities with an extended Poisson kernel and the existence of the extremals

Advanced Nonlinear Studies, 2023
In this article, we first apply the method of combining the interpolation theorem and weak-type estimate developed in Chen et al. to derive the Hardy-Littlewood-Sobolev inequality with an extended Poisson kernel.

Fuzzy integral inequalities on coordinates of convex fuzzy interval-valued functions.

Mathematical biosciences and engineering : MBE, 2021
In this study, we introduce and study new fuzzy-interval integral is known as fuzzy-interval double integral, where the integrand is fuzzy-interval-valued functions (FIVFs). Also, some fundamental properties are also investigated.

A class of completely monotonic functions involving divided differences of the psi and polygamma functions and some applications

, 2009
A class of functions involving the divided differences of the psi function and the polygamma functions and originating from Kershaw's double inequality are proved to be completely monotonic.

Neutrosophic Double Controlled Metric Spaces and Related Results with Application

Fractal and Fractional, 2022
In this paper, the authors introduce the notion of neutrosophic double controlled metric spaces as a generalization of neutrosophic metric spaces. For this purpose, two non-comparable functions, ξ and Γ, are used in triangle inequalities.
