| Abstract: | A type of topological 3-manifold invariants which have been introduced relatively recently with nice integrality properties have also proven to have an interesting behaviour under modular transformations. As such, from a number theory perspective, they provide examples of quantum modular forms. In this seminar I will discuss a second, hidden, modular structure that they possess and how this guides the search for an extension of their definition. |
