A handout for this talk will be available at https://www.rolandvdv.nl/Talks/Stavros25/.
In joint work with Daniel Lopez Neumann we showed how the quantum invariants arising from the twisted double yield a lower bound for the knot genus. We will give an elementary sketch of the construction and discuss further applications.
