Hermite-Hadamard type inequality of convex function has important theoretical significance,and has a wide range of applications.First,we establish a fractional integral equation with Riemann-Liouville.Then we discuss convex functions on Riemann-Liouville fractional integral of Hermite-Hadamard type integral inequality and obtain some results.
