Issue Date: | 2016 | Publisher: | Springer | Project: | info:eu-repo/grantAgreement/FCT/5876/147205/PT | Serial title, monograph or event: | Semigroup Forum | Volume: | 93 | Issue: | 2 | Abstract: | We show that the special Schreier extensions of monoids, with abelian kernel, admit a Baer sum construction, which generalizes the classical one for group extensions with abelian kernel. In order to do that, we characterize the special Schreier extensions by means of factor sets. | URI: | https://hdl.handle.net/10316/44059 | DOI: | 10.1007/s00233-016-9780-2 10.1007/s00233-016-9780-2 |
