Characterized subgroups of the circle group

2025-02-10

Speaker: Giuseppina Barbieri (Univ. Salerno, Italy)

A subgroup \( H \) of the circle group \( \mathbb T \) is said to be characterized by a sequence of integers (\( u_n \)) if \( H=\{x\in\mathbb T : u_nx\to 0\}. \) I would like to present characterized subgroups of \( \mathbb T \) and their significance in various areas of Mathematics,...

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...
