The aim of this paper is to introduce a new extension of preinvexity called
exponentially (m,?1,?2, h1,h2)-preinvexity. Some new integral inequalities
of Hermite-Hadamard type for exponentially (m,?1,?2,h1,h2)-preinvex
functions via Riemann-Liouville fractional integral are established. Also,
some new estimates with respect to trapezium-type integral inequalities for
exponentially (m,?1,?2,h1,h2)-preinvex functions via general fractional
integrals are obtained. We show that the class of exponentially (m,?1,?2,
h1,h2)-preinvex functions includes several other classes of preinvex
functions. We shown by two basic examples the efficiency of the obtained
inequalities on the base of comparing those with the other corresponding
existing ones. At the end, some new error estimates for trapezoidal
quadrature formula are provided as well. This results may stimulate further
research in different areas of pure and applied sciences.
