Hermite–Hadamard type integral inequalities for differentiable m-preinvex and (α,m)-preinvex functions

In this paper, the notion of m  -preinvex and (α,m)(α,m)-preinvex functions is introduced and then several inequalities of Hermite–Hadamard type for differentiable m  -preinvex and (α,m)(α,m)-preinvex functions are established.
