Introduction
En este momento, si bien no he abandonado completamente el estudio de los sistemas bidimensionales de orden entero, tenemos dos direcciones de trabajo perfectamente definidas: 1) El cálculo fraccionario local y sus aplicaciones. 2) El q calculus y las derivadas de tipo q uniforme. Sobre todo relacionadas con la Teoría de la Estabilidad, en particular el Segundo Método de Lyapunov.

In this study, some inequalities of Hermite–Hadamard type for integrals arising in conformable fractional calculus are presented. Numerous known versions are recovered as special cases. We also illustrate our findings via applications to modified Bessel functions, special means, and midpoint approximations.
