On an extension of the operator with Mittag-Leffler kernel

M Al-Refai, D Baleanu - Fractals, 2022 - World Scientific
Dealing with nonsingular kernels is not an easy task due to their restrictions at origin. In this
short paper, we suggest an extension of the fractional operator involving the Mittag-Leffler …

Monotonicity of functions and sign changes of their Caputo derivatives

K Diethelm - Fractional Calculus and Applied Analysis, 2016 - degruyter.com
It is well known that a continuously differentiable function is monotone in an interval [a, b] if
and only if its first derivative does not change its sign there. We prove that this is equivalent …

Equivalence between a time-fractional and an integer-order gradient flow: The memory effect reflected in the energy
