New generalized fuzzy transform computations for solving fractional partial differential equations arising in oceanography

open access: yesJournal of Ocean Engineering and Science, 2023
This paper presents a study of nonlinear waves in shallow water. The Korteweg-de Vries (KdV) equation has a canonical version based on oceanography theory, the shallow water waves in the oceans, and the internal ion-acoustic waves in plasma.

The Upper and Lower Solution Method for a Class of Interval Boundary Value Problems

open access: yesAxioms, 2021
In this paper, the upper and lower solution method is proposed in order to solve the second order interval boundary value problem. We study first a class of linear interval boundary value problems and then investigate a class of nonlinear interval ...

Generalized Euler-Lagrange Equations for Fuzzy Fractional Variational Problems under gH-Atangana-Baleanu Differentiability

open access: yesJournal of Function Spaces, 2018
We study in this paper the Atangana-Baleanu fractional derivative of fuzzy functions based on the generalized Hukuhara difference. Under the condition of gH-Atangana-Baleanu fractional differentiability, we prove the generalized necessary and sufficient ...

Intuitionistic fuzzy evolution problem with nonlocal conditions [PDF]

open access: yesNotes on IFS
In this manuscript, we investigate the existence and uniqueness of solutions for the intuitionistic fuzzy evolution problem with non-local conditions, employing a generalized Caputo derivative ^C_{gH}D_{0^+}^γ of order 0 < γ < 1. Our methodology involves
