Title: | Approximate Hagemann–Mitschke Co-operations | Authors: | Rodelo, Diana Van der Linden, Tim |
Issue Date: | 2013 | Publisher: | Springer | Project: | info:eu-repo/grantAgreement/FCT/COMPETE/132981/PT | Serial title, monograph or event: | Applied Categorical Structures | Volume: | 22 | Issue: | 5-6 | Abstract: | We show that varietal techniques based on the existence of operations of a certain arity can be extended to n-permutable categories with binary coproducts. This is achieved via what we call approximate Hagemann–Mitschke co-operations, a generalisation of the notion of approximate Mal’tsev co-operation [2]. In particular, we extend characterisation theorems for n-permutable varieties due to J. Hagemann and A. Mitschke [8, 9] to regular categories with binary coproducts. | URI: | https://hdl.handle.net/10316/43869 | DOI: | 10.1007/s10485-013-9359-y 10.1007/s10485-013-9359-y |
