Baer sums of special Schreier extensions of monoids / N. Martins Ferreira, A. Montoli, M. Sobral. - In: SEMIGROUP FORUM. - ISSN 0037-1912. - 93:2(2016 Oct), pp. 403-415. [10.1007/s00233-016-9780-2]
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.
