The Nine Lemma and the push forward construction for special Schreier extensions of monoids with operations
| Resumo: | We show that the Nine Lemma holds for special Schreier extensions of monoids with operations. This fact is used to obtain a push forward construction for special Schreier extensions with abelian kernel. This construction permits to give a functorial description of the Baer sum of such extensions. |
