Abstract
Local and global existence and uniqueness of mild solution for the fractional integro-differential equations of mixed type with delay are proved by using a family of solution operators and the contraction mapping principle on Banach space. TheBolza optimal control problem of a corresponding controlled system is solved. The Gronwall lemma with singular and time lag is derived to be tool for obtaining a priori estimate. In addition, the application to the fractional nonlinear heat equation is shown.

Summary
We consider fractional integro-differential equations of mixed type with delay;. Many research groups have studied and reported on integro-differential systems and fractional differential systems. These reports include the proof of the existence and uniqueness of a classical solution of an integro-differential equation by Chonwerayuth and a portion of work on the nonlinear impulsive integro-differential equations of mixed type by Wei.W. in 2009, Gisele M.Mophou proved existence and uniqueness of mild solution to impulsive fractional differential equations.
