具有局部单位的环上的可逆单位双模及群的相关exact sequences

Invertible unital bimodules over rings with local units, and related exact sequences of groups

L. El Kaoutit, J. Gómez-Torrecillas

摘要:

受Miyashita的启发,给出了局部单位集相同的环的扩张$R \subseteq S$,构造了四个与Picard群$R$和$S$相关的正合群序列.

英文摘要:

Given an extension $R \subseteq S$ of rings with same set of local units, inspired by the works of Miyashita, we construct four exact sequences of groups relating Picard's groups of $R$ and $S$.
