Dynamics and Stability of $\Xi$-Hilfer Fractional Fuzzy Differential Equations with Impulses

Autor: Kangarajan K., Dvivek Vivek, Elsayed Elsayed, Ravichandran Vıvek

Publikováno v: Communications in Advanced Mathematical Sciences, Vol 6, Iss 3, Pp 115-127 (2023)

This paper deals with the existence, uniqueness, and Ulam-stability outcomes for $\Xi$-Hilfer fractional fuzzy differential equations with impulse. Further, by using the techniques of nonlinear functional analysis, we study the Ulam-Hyers-Rassias sta

On Fuzzy Differential Equations with Finite Delay via $\psi$-type Riemann-Liouville Fractional Derivative

Autor: Kangarajan K., Dvivek Vivek, Elsayed Elsayed

Publikováno v: Communications in Advanced Mathematical Sciences, Vol 5, Iss 1, Pp 8-11 (2022)

In the article, the existence of a solution for a class of boundary value problem for a fuzzy differential equation with finite delay is discussed. By applying the contraction mapping principle, we gain an existence of a solution.
