Existence of mild solutions for fractional non-instantaneous impulsive integro-differential equations with nonlocal conditions

Arshi Meraj, Dwijendra N. Pandey

This paper is concerned with the existence of mild solutions for a class of fractional semilinear integro-differential equations having non-instantaneous impulses. The result is…

Estimation of different entropies via Abel–Gontscharoff Green functions and Fink’s identity using Jensen type functionals

Khuram Ali Khan, Tasadduq Niaz, Đilda Pečarić, Josip Pečarić

In this work, we estimated the different entropies like Shannon entropy, Rényi divergences, Csiszár divergence by using Jensen’s type functionals. The Zipf’s–Mandelbrot law and…

Unbalanced multi-drawing urn with random addition matrix

Aguech Rafik, Selmi Olfa

In this paper, we consider a two color multi-drawing urn model. At each discrete time step, we draw uniformly at random a sample of m…

Approximation of fixed point of multivalued ρ-quasi-contractive mappings in modular function spaces

Godwin Amechi Okeke, Safeer Hussain Khan

The purpose of this paper is to extend the recent results of Okeke et al. (2018) to the class of multivalued

The implicit midpoint rule for nonexpansive mappings in 2-uniformly convex hyperbolic spaces

H. Fukhar-ud-din, A.R. Khan

The purpose of this paper is to introduce the implicit midpoint rule (IMR) of nonexpansive mappings in 2- uniformly convex hyperbolic spaces and study its convergence. Strong and

On abstract Hilfer fractional integrodifferential equations with boundary conditions

Sabri T.M. Thabet, Bashir Ahmad, Ravi P. Agarwal

In this paper, we study a Cauchy-type problem for Hilfer fractional integrodifferential equations with boundary conditions. The existence of solutions for the given problem is…

Remarks on the critical nonlinear high-order heat equation

Tarek Saanouni

The initial value problem for a semi-linear high-order heat equation is investigated. In the focusing case, global well-posedness and exponential decay are obtained. In the…

Approximative K-atomic decompositions and frames in Banach spaces

Shah Jahan

L. Gǎvruţa (2012) introduced a special kind of frames, named K-frames, where K is an operator, in Hilbert spaces, which is significant in frame theory and has many applications…

Existence of self-similar solutions of the two-dimensional Navier–Stokes equation for non-Newtonian fluids

Dongming Wei, Samer Al-Ashhab

The reduced problem of the Navier–Stokes and the continuity equations, in two-dimensional Cartesian coordinates with Eulerian description, for incompressible non-Newtonian fluids…

Coupled fixed points and coupled best proximity points for cyclic Ćirić type operators

Adrian Magdaş

The purpose of this paper is to study the coupled fixed point problem and the coupled best proximity problem for single-valued and multi-valued contraction type operators defined…

Subcommuting and comparable iterative roots of order preserving homeomorphisms

Veerapazham Murugan, Murugan Suresh Kumar

It is known that the iterative roots of continuous functions are not necessarily unique, if it exist. In this note, by introducing the set of points of coincidence, we study the…

Strong consistency of a kernel-based rule for spatially dependent data

Ahmad Younso, Ziad Kanaya, Nour Azhari

We consider the kernel-based classifier proposed by Younso (2017). This nonparametric classifier allows for the classification of missing spatially dependent data. The weak…

On the primeness of near-rings

Khalid H. Al-Shaalan

In this paper, we study the different kinds of the primeness on the class of near-rings and we give new characterizations for them. For that purpose, we introduce new concepts…

Multivariate Hardy and Littlewood inequalities on time scales

Ammara Nosheen, Aneela Nawaz, Khuram Ali Khan, Khalid Mahmood Awan

In the paper we extend some Hardy and Littlewood type inequalities on time scales for the function of n…
