We use the framework of SLE curves in $AdS_2$ to classify these particle trajectories in terms of their boundary conditions.]]><![CDATA[Francesca Ferrari, 2019/11/18, 15h, $3d$ Modularity]]>We find and propose an explanation for a large variety of modularity-related symmetries in problems of $3$-manifold topology and physics of $3d$ $N=2$ theories, where such structures a priori are not manifest.]]><![CDATA[Michele Cirafici, 2019/10/22, 16h, Supersymmetric line operators and their spectral problem]]>I will discuss BPS invariants associated with quantum line operators in certain supersymmetric quantum field theories. Such operators can be specified via geometric engineering in the UV by assigning a path on a certain curve. In the IR they are described by representation theory data. I will discuss the associated BPS spectral problem and the relevant indices.]]>
