© 2023 World Scientific Publishing Company.In this paper, we study the primary intuitionistic fuzzy ideal, the intuitionistic fuzzy ideal expansion and ?-primary intuitionistic fuzzy ideal which assemble prime intuitionistic fuzzy ideals and primary intuitionistic fuzzy ideals. Some properties of them are investigated. Also, we scrutinize the relationships of ?-primary intuitionistic fuzzy ideal and ?-primary ideal of a commutative ring R. Moreover, we give a fundamental result about correspondence theorem for ?-primary intuitionistic fuzzy ideals. Further, we introduce 2-absorbing ?-primary intuitionistic fuzzy ideals which are the generalization of 2-absorbing intuitionistic fuzzy ideals and 2-absorbing primary intuitionistic fuzzy ideals. Some properties of them are obtained.
