A new class of MT (r;g,m,φ)- preinvex functions is introduced and some new integral inequalities for the left-hand side of Gauss-Jacobi type quadrature formula involving products of two MT (r;g,m,φ)- preinvex functions are given. Moreover, some generalizations of Hermite-Hadamard type inequalities for products of two MT (r;g,m,φ)- preinvex functions via Riemann-Liouville fractional integrals are established. These general inequalities give us some new estimates for the left-hand side of Gauss-Jacobi type quadrature formula and Hermite-Hadamard type fractional integral inequalities. At the end, some conclusions and future research are given.

Keywords: Hermite-Hadamard type inequality; Hölder’s inequality; Minkowski’s inequality; Cauchy’s inequality; Power mean inequality; Riemann-Liouville fractional integral; s-convex function in the second sense; m-invex; P -function
