## Nonlinear boundary value problems of fractional functional integro-differential equations.(English)Zbl 1268.34021

Summary: We consider the existence of generalized solutions for fractional functional integro-differential equations of mixed type with nonlinear boundary value conditions. By establishing a new comparison theorem and applying the monotone iterative technique, we show the existence of extremal generalized solutions.
