The main objective of this research article is to study the analytical solution of the
Pythagorean fuzzy wave equation under the generalized Hukuhara partial differentiability …

I tried to use my all knowledge and experiences during 22 years on the fuzzy subjects, to
write this book. To this end, I studied many sources that all are in the sources section but the …

A novel modification of the variational iteration method (VIM) is proposed by means of the
Laplace transform. Then the method is successfully extended to fractional differential …

In this paper, the fuzzy variational problem and fuzzy optimal control problem are
considered. The granular Euler–Lagrange condition for the fuzzy variational problem and …

The non-classical calculi such as q-calculus, fractional calculus and q-fractional calculus
have been hot topics in both applied and pure sciences. Then some new linear and …

This paper presents a new approach for obtaining triangular solutions of linear partial
differential equations with fuzzy coefficients. Our approach is based on employing the …

The use of fuzzy partial differential equations has become an important tool in which
uncertainty or vagueness exists to model real-life problems. In this article, two numerical …

This paper presents a comprehensive study of the linguistic Z-graph, which is a novel
framework designed to analyze linguistic structures within social networks. By integrating …

A universal approach by Laplace transform to the variational iteration method for fractional
derivatives with the nonsingular kernel is presented; in particular, the Caputo-Fabrizio …

The variational iteration method is successfully extended to the case of solving fractional
differential equations, and the Lagrange multiplier of the method is identified in a more …
