Issue Date: | 2013 | Publisher: | Springer | Project: | PEst-C/MAT/UI0324/2013 | Serial title, monograph or event: | Applied Categorical Structures | Volume: | 22 | Issue: | 5-6 | Abstract: | In this paper we use Janelidze’s approach to the classical theory of topological coverings via categorical Galois theory to study coverings in categories of relational algebras. Moreover, we present characterizations of effective descent morphisms in the categories of M-ordered sets and of multi-ordered sets. | URI: | https://hdl.handle.net/10316/43758 | DOI: | 10.1007/s10485-013-9349-0 10.1007/s10485-013-9349-0 |
