Mittag-Leffler functions and convex ordering
Rui Ferreira, Thomas Simon
The monotonicity of the Mittag-Leffler function with respect to the parameter is investigated, via some convex ordering properties for related random variables. In partic…
On the log-concavity of the Wright function
Rui A. C. Ferreira, Thomas Simon
We investigate the log-concavity on the half-line of the Wright function in the probabilistic setting and Applications are given to the constru…
Convolution of beta prime distribution
Rui A. C. Ferreira, Thomas Simon
We establish some identities in law for the convolution of a beta prime distribution with itself, involving the square root of beta distributions. The proof of these identities rel…
Generalized Discrete Operators
Rui A. C. Ferreira
We define a class of discrete operators that, in particular, include the delta and nabla fractional operators.
Sign of the solutions of linear fractional differential equations and some applications
Rui A. C. Ferreira
In this work we wish to highlight some consequences of a recent result proved in [N. D. Cong and H. T. Tuan, Generation of nonlocal fractional dynamical systems by fractional diffe…
Stability of a class of entropies based on fractional calculus
Rui A. C. Ferreira
In this work we argue about the Lesche stability of some systems, that are motivated by the use of fractional derivatives.
