A truncated $\mathcal{V}$-fractional derivative in $\mathbb{R}^n$

Abstract

Using the six parameters truncated Mittag-Leffler function, we introduce a convenient truncated function to define the so-called truncated $\mathcal{V}$-fractional derivative type. After a discussion involving some properties associated with this derivative, we propose the derivative of a vector valued function and define the $\mathcal{V}$-fractional Jacobian matrix whose properties allow us to say that: the multivariable truncated $\mathcal{V}$-fractional derivative type, as proposed here, generalizes the truncated $\mathcal{V}$-fractional derivative type and can bee extended to obtain a truncated $\mathcal{V}$-fractional partial derivative type. As applications we discuss and prove the change of order associated with two index i.e., the commutativity of two truncated $\mathcal{V}$-fractional partial derivative type and propose the truncated $\mathcal{V}$-fractional Green's theorem.
