Operations in Khovanov homology

2024-10-09

Speaker: Federico Moran (Universidad Autónoma de Madrid, Spain)

I will give an introduction to Khovanov homology, a link invariant introduced by Khovanov twenty-five years ago, and then explain how to construct operations on this link invariant following the work of Lipshitz and Sarkar on Khovanov spectra....

Gelfand-Tsetlin representations and Drinfeld categories

2024-10-09

Speaker: Lucas Queiroz Pinto (Univ. São Paulo, Brazil)

Within the Theory of Gelfand-Tsetlin modules, the Drinfeld Categories were introduced in 2017 by V. Futorny et al. to demonstrate that every irreducible 1-singular Gelfand-Tsetlin module is isomorphic to a subquotient of the Universal 1-singular module.The authors also noted...

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...
