QM Research Seminar: Braid Group Representations and Orbifoldization

5 okt

Speaker: Jiahe Cai, University of Copenhagen Abstract: Let G be a finite group. By evaluation of a once-extended 3-2-1-dimensional G-equivariant topological field theory Z on the circle one obtains a G-ribbon category C. From a homotopy G-fixed point in this G-ribbon category C, we can construct two representations of framed braid groups fBn with n strands for any n ≥ 1: 1) We can construct a representation of fBn by evaluating Z on genus zero surfaces with G-bundle decoration. 2) We can orbifoldize the G-ribbon category C and obtain the fBn representation algebraically by using the braiding and twist of the orbifold category. We prove that these two representations are equivalent.

QM Research Seminar: A sheaf theoretic approach to homology manifolds and Poincaré and Atiyah duality

9 okt

Speaker: Marco Volpe (MPIM Bonn) Abstract: Poincaré and Atiyah duality theorems are fundamental results in the study of the (co)homology of smooth manifolds. However, due to their purely cohomological nature, one may naturally wonder whether it is necessary to impose geometric conditions on a topological space to ensure the validity of these theorems. In this presentation, we will review and reinterpret both Poincaré and Atiyah duality theorems using the framework of sheaves of infinity categories. We will employ the formalism of six operations to extend these duality theorems beyond the realm of manifolds. Even more, we will provide a comprehensive characterization of the class of topological spaces that satisfy Poincaré and Atiyah duality. This class essentially consists of what are known as integral homology manifolds. This is a joint work with Markus Land.

QM Research Seminar: Stability conditions on free abelian quotients

16 okt

Speaker: Hannah Dell (University of Edinburgh) Abstract: The space of Bridgeland stability conditions on a given triangulated category is a complex manifold, which gives us a way to extract geometry from homological algebra. An explicit description is only known in a few cases. In this talk, I will discuss two approaches to studying stability conditions on derived categories of surfaces that are free quotients by finite abelian groups. One method is via Le Potier functions, which characterise the existence of slope-semistable sheaves. The second method uses Deligne’s notion of group actions on triangulated categories to describe a connected component of so-called geometric stability conditions inside the stability manifold of these free abelian quotients when the cover has finite Albanese morphism. A consequence of this is a disproof of the expectation that surfaces with irregularity 0 always admit a wall of the geometric chamber. This is based on arXiv:2307.00815.

QM Research Seminar: Analytically continued Chern-Simons theory on plumbed 3-manifolds

23 okt

Speaker: Pavel Putrov (ICTP) Abstract: I will present a finite-dimensional model for analytically continued Chern-Simons theory on closed 3-manifolds that are described by plumbing trees. From this model, one can define a collection of topological invariants labeled by pairs of flat connections and valued in formal power series with integral coefficients. The coefficients can be roughly interpreted as counting gradient descent flows with respect to Chern-Simons functional in the space of SL(2,C) connections on the 3-manifold. I will also comment on a possible categorification, which can be interpreted as a finite-dimensional model of Fukaya-Seidel category of Chern-Simons functional on the space of SL(2,C) connections.

Introduction to Ucloud

26 okt

UCloud is a powerful interactive digital research environment, which provides an intuitive graphical user interface to give easy access to interactive high-performance computing and tools. Advantages for students include: • cloud services (compute and storage) accessible via every type of device, from workstations to laptops and tablets, no need of local software installation • data can be shared in project workspaces, with restricted access to computational resources and teaching materials • high performance computing can be performed at all the level of expertise • easy to share data with collaborators, class mate, teachers in secure virtual environments • support from eScience Center In this seminar Federica Lo Verso will give a basic introduction to UCloud, including how to access the platform, the softwares and manage files and folders.

QM Research Seminar: Trace map on chiral Weyl algebras

30 okt

Speaker: Zhengping Gui (ICTP) Abstract: We construct a trace map on the chiral homology of chiral Weyl algebra for any smooth Riemann surface. Our trace map can be viewed as a chiral version of the deformed HKR quasi-isomorphism. This also provides a mathematical rigorous construction of correlation function for symplectic bosons in physics. We calculate some examples of trace maps with one insertion and find they are closely related to the variation of analytic torsion for holomorphic bundles on Riemann surfaces.
