A tour on quantum topology and categorification
2025-02-19
Speaker: Pedro Vaz (UC Louvain, Belgium)
Quantum topology is a generic term used to designate algebraic-topological constructions that are, in some broad sense, close to the Jones polynomial and its variants.In this talk, I will give an overview of topological quantum invariants and their categorification, from their historical...
Linking the co-colonization replicator model to ecological data
2025-02-21
Speaker: Erida Gjini (CEMAT, IST-Univ. Lisboa)
In the last years, we have developed and studied an N-strain SIS system with co-colonization and strain interactions, leading to a replicator equation [4]. Applying slow-fast dynamics, we have simplified this high-dimensional eco-epidemiological system, finding parallels between microbial...

Normed categories
2025-03-11
Speaker: Dirk Hofmann (CIDMA, Univ. Aveiro)
In this talk we investigate the notion of normed category: a category where each hom-set \( X(A,B) \) comes equipped with a norm \( X(A,B)\to [0, \infty] \), subject to suitable axioms. As suggested by Lawvere (1973), we treat normed categories consequentially as categories enriched in...
