【Abstract】 The method of upper and lower solutions with reversed ordering combined with monotone iterative technique is empolyed to study the existence of solutions of a class of first-order functional differential equations with integral boundary conditions.Under suitable conditions,a new existence theorem is obtained,which generalized the known results.An example also is given to illustrate the theorem obtained.更多还原
