Existence of solutions for fractional q-difference equations [PDF]

open access: yes, 2023
In this paper, we obtain some existence results for the integral boundary value problems of nonlinear fractional q-difference equations. The differential operator is taken in the Riemann-Liouville sense.  Mathematics Subject Classification (2010): 39A13,

Major Remark on Unique Fixed‐Point Theorems via Interpolative and Rational Contractions in Super Metric Spaces and A New Approach to the Interpolative Contractions

open access: yesJournal of Function Spaces, Volume 2026, Issue 1, 2026.
This paper presents a critical analysis of several recent fixed‐point results involving interpolative and rational contractions in super metric spaces and related frameworks. We first show that certain claimed fixed‐point theorems, including a result concerning (ρ, λ)‐interpolative Kannan contractions, do not provide genuinely new contributions, since ...

The existence and uniqueness of solutions to a functional equation arising in psychological learning theory

open access: yesDemonstratio Mathematica, 2023
The paradigm of choice practice represents the psychological theory of learning in the development of moral judgment. It is concerned with evaluating the implications of several choices and selecting one of them to implement.

Best Proximity Point Results in Graphical Metric Space and Application

open access: yesJournal of Function Spaces, Volume 2026, Issue 1, 2026.
This article introduces and investigates the notion of (Ψ, K)‐quasi graphical proximal contraction mappings within the framework of graphical metric spaces. We establish several best proximity point theorems for such mappings under appropriate structural and completeness assumptions.

Investigating Mild Solutions for Noninstantaneous Impulsive Caputo Fractional Integro‐Differential Equations

open access: yesJournal of Function Spaces, Volume 2026, Issue 1, 2026.
In this paper, the existence of mild solutions for a class of noninstantaneous impulsive Caputo fractional integro‐differential equations subject to nonlocal conditions in Banach spaces is investigated. The problem is formulated in a general infinite‐dimensional setting so that systems involving memory effects and impulses acting over finite intervals ...
