Quantum Invariants of Ribbon Surfaces in $4$ -Dimensional $2$ -Handlebodies

Anna Beliakova, Marco De Renzi, Quentin Faes

We use unimodular ribbon categories to construct quantum invariants of ribbon surfaces in $4$ -dimensional $2$ -handlebodies up to $1$ -isotopy. In the process, we recover invariants…

Non-factorizable ribbon Hopf Algebras

Quentin Faes, Maksymilian Manko

Building on the work of Nenciu we provide examples of non-factorizable ribbon Hopf algebras, and introduce a stronger notion of non-factorizability. These algebras are designed to…
