### Vorträge

Date | Speaker | Title, Abstract |
---|---|---|

September 16 | Vivek Singh (Warschau) | Chern-Simons invariants, Multi-boundary Entanglement and Knot-Quiver Correspondence |

First, I will give a brief introduction to knot theory and its connection to Chern-Simons quantum field theory. Then I will briefly review my research works and particular focus on the recent developments on entanglement entropy associated with multi-boundary link complements. My plan to highlight the interesting relationship between the volume of hyperbolic link complements to non-zero entanglement negativity. In the end, I will briefly discuss Knot-Quiver correspondence. | ||

Wednesday, October 2 Hörsaal, 2 p.m. |
Mauricio Romo (Beijing) | Enumerative invariants from exponential networks |

I will review some aspects of exponential networks associated to CY 3-folds described by conic bundles. In particular I will focus on the relation between exponential networks and the so-called nonabelianization map which serves as a tool to connect counting of 3d-5d BPS states with certain classes of generalized DT invariants. | ||

October 21 | Andrew Bruce (Luxemburg) | (Z-manifolds: recent developments and ongoing work _{2})^{n} |

A locally ringed space approach to coloured supermanifolds was
recently initiated by Grabowski and Poncin together with a collection of
collaborators. We must comment that the theory, while a natural extension of
the theory of supermanifolds, is not always straightforward nor trivial. While
the basic ideas are now in place, we will report on some recent developments in
the general theory. I will then discuss applications of (Z-manifolds to mixed
symmetry tensors as found in string theory.
