Shani Meynet (Uppsala University) - Boundary geometry and topological defects

In this talk, I will explore the relation between topological operators and branes wrapped on torsional cycles. By means of some explicit examples, in 4,5 and 7 dimensions, I will present the main ideas behind the geometric engineering dictionary relating branes and, in general, higher-form symmetries. I will show how torsional cycles of the boundary geometry correspond to topological operators and how their higher linking numbers can be associated with anomalies. On top of this, I will discuss symmetries not captured by branes, but by isometries of the engineering geometry. Taking them into account might shed some light on possible extensions of the SymTFT derived from geometry by dimensional reduction methods.
