Volume 3, Issue 3 , September 2021, , Pages 33-38
Abstract
This paper aims to prove that the Lipschitz constant in the Banach contraction principle belongs to the whole interval [0, 1) for all the six classes of spaces viz. metric spaces, b-metric spaces, partial metric spaces, partial b-metric spaces, metric like space, and finally for more general spaces called ...

Volume 2, Issue 1 , April 2020, , Pages 35-42
Abstract
In this paper, we investigate the behaviour of e-convex sets and e-affine sets. Moreover, some notions like S(e,a,ρ,α) and e-affine cones are introduced and discussed. We complete with a role of above sets in linear idempotent maps. Read More28. Exact controllability and continuous dependence of solution of a conformable fractional control system
Volume 4, Issue 2 , April 2022, , Pages 35-46
Abstract
The exact controllability of a conformable fractional differential system is established in this paper. The system is described by a non-densely defined linear part satisfying the Hille Yosida condition, and a control term appearing in the nonlinear part. The existence of mild solution and exact controllability ... Read More29. Weakly principally quasi-Baer rings and generalized triangular matrix rings
Volume 3, Issue 1 , February 2021, , Pages 39-45
Abstract
A ring $R$ is called weakly principally quasi-Baer or simply (weakly p.q.-Baer) if the right annihilator of a principal right ideal is right $s$-unital by right semicentral idempotents. In this paper, we characterize when a generalized triangular matrix ring is a weakly p.q.-Baer ... Read More30. On quasi hemi-slant submanifolds of LP-cosymplectic manifolds
Volume 3, Issue 3 , September 2021, , Pages 39-49
Abstract
In this paper, we define and study quasi Hemi-slant submanifolds of Lorentzian almost contact metric manifolds. We mainly concern with quasi Hemi-slant submanifolds of LP-cosymplectic manifolds. First, we find conditions for integrability of distributions involved in the definition of quasi hemislant ... Read More31. Some coupled coincidence point results in partially ordered metric spaces

In this paper, we introduce the notion of partial-compatibility of mappings in an ordered partial metric space and use this notion to establish coupled coincidence point theorems for $\phi$-mixed monotone mappings satisfying a nonlinear contraction condition. Our consequences is an extension of the results ... Read More32. Multiplicity results for the nonlinear p-Laplacian fractional boundary value problems

Abstract
This paper investigates the existence of single and multiple positive positive solutions of fractional differential equations with p-Laplacian by means of the Green's function properties, the Guo-Krasnosel'skii fixed point theorem, the monotone iterative technique accompanied by established sufficient ...

Volume 1, Issue 1 , February 2019, , Pages 44-49
Abstract
Let A be a Banach algebra and X be a Banach A-bimodule. In this paper we investigate the stability of the cosine type functional equation φ(ab,a·y+x·b)=φ(ab,x·b-a·y)=2φ(a,x)φ(b,y),on module extension Banach algebra U=A+X. Read More34. Homotopy Perturbation Method with the help of Adomian decomposition method for nonlinear problems
Volume 4, Issue 1 , January 2022, , Pages 45-51
Abstract
This paper concerns He's Homotopy Perturbation Method (HPM) which has been applied to solve some nonlinear differential equations. In HPM, at first, we construct a homotopy that satisfies an equation which is called the perturbation equation. Moreover, in this method, the solution is considered as power ... Read More35. A proof of the Cauchy--Schwarz inequality from the change of reference frame
Volume 3, Issue 1 , February 2021, , Pages 46-47
Abstract
Inspired by [1] a proof of the Cauchy--Schwarz inequality is given by considering the transformation between two different inertial reference frames. Read More36. Notes on the stability of multimixed additive-quartic mappings

Abstract
In this article, we prove the Hyers-Ulam stability of multimixed additive-quartic functional equations in the setting of Banach spaces by applying a fixed point method and moreover we generalize some known results. Read More37. Stability of quartic functional equation in paranormed spaces
Volume 3, Issue 1 , February 2021, , Pages 48-58
Abstract
In this paper, we prove the Ulam-Hyers stability of the following quartic functional equation in paranormed spaces using both direct and fixed point methods. Read More38. Partially ordered cone metric spaces and coupled fixed point theorems via $\alpha$-series
Volume 1, Issue 1 , February 2019, , Pages 50-61
Abstract
This research tends to focus on proving the results of coupled fixed point in partially ordered cone metric spaces by imposing some condition on a self-mapping and a sequence of mappings via $\alpha$-series. The $\alpha$-series are wider than the convergent series. Furthermore, an example ... Read More39. Some approximations for an equation in modular spaces
Volume 3, Issue 3 , September 2021, , Pages 51-64
Abstract
In this paper, we introduce and obtain the general solution of a new mixed type quadratic-cubic functional equation. We investigate the stability of such functional equations in the modular space $X_\rho$ by applying $\Delta_2$-condition and the Fatou property (in some results) in the modular function ...

Volume 4, Issue 1 , January 2022, , Pages 53-70
Abstract
The aim of this paper is to prove a common fixed point theorem for two pairs of $\omega$-compatible and $\omega$-weakly compatible maps for extending and generalizing the results of Murthy and Prasad [12] in modular metric spaces. The main result is also illustrated by an example to demonstrate the degree ... Read More41. The coincidence point results and rational contractions in E(s)-distance spaces
Volume 3, Issue 2 , June 2021, , Pages 55-67
Abstract
The purpose of this article is to clarify the concept of semi-interior points of positive cones by presenting some results and examples in this context. Moreover, the new concept of E(s)-distance spaces is defined, which generalizes $E$-metric spaces. In addition, some coincidence point results ... Read More42. Fixed point theorems for occasionally weakly compatible maps in neutrosophic metric spaces
Volume 4, Issue 2 , April 2022, , Pages 57-69
Abstract
In 2008, Al-Thagafi and Shahzad introduced the notion of Occasionally Weakly Compatible mappings (shortly OWC maps) which is more general than all the commutativity concepts. The purpose of the paper is to obtain common fixed point theorems in Neutrosophic metric spaces by using OWC maps. Read More43. Cohen’s factorization theorem for ternary Banach algebras

Volume 3, Issue 4 , December 2021, , Pages 63-83
Abstract
In this paper, by using norms (t-norms and t-conorms), we introduce the notions of bifuzzy d-algebras and bifuzzy d-ideals of d-algebras and investigate several interesting properties. Next, we consider their intersection and product. Finally, we obtain some results about them under d-algebra homomorphisms. Read More45. Controlled g-frames in Hilbert C*-modules
Volume 3, Issue 3 , September 2021, , Pages 65-82

The controlled frame was introduced in 2010 by Balazs et al. [2], with the aim to improve the efficiency of the iterative algorithms constructed for inverting the frame operator. In this paper, the concept of controlled g-frames is introduced in Hilbert C*-modules. The equivalent condition for a controlled ... Read More46. Biflatness of Banach algebras modulo an ideal

Abstract
Biflatness of Banach algebras is one of the important topics in the study of cohomological properties of Banach algebras. This concept has a close relationship with the amenability of Banach algebras. In this paper, we introduce a new notion namely biflatness of Banach algebras modulo closed ideals. ... Read More47.
