Right-preordered groups from a categorical perspective

2024-10-22

Speaker: Maria Manuel Clementino (CMUC, Univ. Coimbra)

Following the study of the categorical features of preordered groups of [1], in this talk we study the category of right-preordered groups and monotone homomorphisms. We start by showing that this category has exactly the same exactness properties as the category of preordered groups....

Enriched aspects of the Mal'tsev Property

2024-10-22

Speaker: Diana Rodelo (CMUC & Univ. Algarve)

The aim of this work is to explore the 1-dimensional algebraic Mal'tsev property from an Ord-enriched point of view. A 1-dimensional (regular) Mal'tsev category [2, 1] may be characterised through nice properties on (internal) relations such as:- every reflexive relation \( R \rightarrowtail...
