Differential equations with tempered Ψ-Caputo fractional derivative [PDF]

open access: yesMathematical Modelling and Analysis, 2021
In this paper we define a new type of the fractional derivative, which we call tempered Ψ−Caputo fractional derivative. It is a generalization of the tempered Caputo fractional derivative and of the Ψ−Caputo fractional derivative.
