Tóm tắt: In this talk, we study the reducibility index under flat homomorphism of Noetherian rings. Especially, the localization, the polynomial extension, and the completion of base ring are studied. We also clarify the relation among the reducibility index of module, that of the completion of module, and the sum-reducibility index of the Matlis dual of module. Some related problems are given to discuss.
