摘要
The existence of at least one solution and the existence of extreme solutions of periodic boundary value problems for first_order integro_differential equations of mixed type are studied,in the presence of generalized upper and lower solutions. The discussion is based on new comparison theorems and coincidence degree and monotone iterative methods.
