In this memory, we will focus on the study of inequality of the
Hermite-Hadamard for standard difference of convexity.
In the first chapter, we recall some definitions of classical
convexity, as well as some classes of functions.
In the second chapter, we discuss some classical Hermite-
Hadamard types of inequalities.
While the last chapter will be entierly devoted some
fractional Hermite-Hadamard inequalities.
