Since the term “Fuzzy differential equations”(FDEs) emerged in the literature in 1978,
prevailing research effort has been dedicated not only to the development of the concepts …

This paper deals with the solutions of fuzzy fractional differential equations (FFDEs) under
Riemann–Liouville H-differentiability by fuzzy Laplace transforms. In order to solve FFDEs, it …

Fuzzy differential equations (FDEs) are the general concept of ordinary differential
equations. FDE seems to be a natural way to model the propagation of cognitive uncertainty …

In this paper, we apply the concept of Caputo's H-differentiability, constructed based on the
generalized Hukuhara difference, to solve the fuzzy fractional differential equation (FFDE) …

Fuzzy fractional differential has the strength to capture the senses of memory and
uncertainty simultaneously involved in dynamical systems. However, a solution for fuzzy …

Analytical studies of fuzzy fractional differential equations (FFDEs) of two different
independent fractional orders are often complex and difficult. It is essential to develop …

In this research article, we discuss an important class of modern differential equations in the
Pythagorean fuzzy environment, called the Pythagorean fuzzy fractional differential …

In this paper, a novel coronavirus infection system with a fuzzy fractional differential equation
defined in Caputo's sense is developed. By using the fuzzy Laplace method coupled with …

A natural way to model dynamic systems under uncertainty is to use fuzzy initial value
problems (FIVPs) and related uncertain systems. In this paper, we express the fuzzy Laplace …

In this paper, we introduce two definitions of the differentiability of type-2 fuzzy number-
valued functions of fractional order. The definitions are in the sense of Riemann–Liouville …
