| Quantum modularity of 3-manifold invariants |
| Speaker: | Francesca Ferrari |
| Abstract: | Recently, a new homological invariant of 3-manifolds -
which categorifies the Witten-Reshetikhin-Turaev invariant - has been
discovered. This is known as the homological block. In this talk, I will explain the importance of quantum modular forms in the study of
3-manifold invariants and describe, in particular, how to predict
topological data of 3-manifolds via the quantum modular properties of
the associated homological block. The talk will be based on the article
1809.10148 and work in progress with Cheng, Chun, Feigin, Gukov, and
Harrison.

| Testing Swampland Conjectures |
| Speaker: | Hirosi Ooguri (Caltech & Kavli IPMU) |
| Abstract: | Over the last fourteen years, a variety of swampland conditions have been proposed with various degrees of rigor. In this talk, I will discuss tests of some of these conjectures that do not rely on specific string theory constructions. They include constraints on symmetry, strength of gravitational couplings, cobordism between theories, and issues with lower dimensional theories. |
