These are a set of lecture notes on generalized global symmetries in quantum field theory.
The focus is on invertible symmetries with a few comments regarding non-invertible …

In this lecture note, we give a basic introduction to the rapidly develo** concepts of
generalized symmetries, from the perspectives of both high energy physics and condensed …

We survey recent developments in a novel kind of generalized global symmetry, the non-
invertible symmetry, in diverse spacetime dimensions. We start with several different but …

We propose a general framework to characterize gapped infra-red (IR) phases of theories
with non-invertible (or categorical) symmetries. In this paper we focus on (1+ 1) d gapped …

Recently it has been observed that branes in geometric engineering and holography have a
striking connection with generalized global symmetries. In this paper we argue that branes …

We study anomalies of non-invertible duality symmetries in both 2d and 4d, employing the
tool of the Symmetry TFT. In the 2d case we rephrase the known obstruction theory for the …

The global symmetries of a D-dimensional quantum field theory (QFT) can, in many cases,
be captured in terms of a (D+ 1)-dimensional symmetry topological field theory (SymTFT). In …

We study the holographic dual of a topological symmetry operator in the context of the
AdS/CFT correspondence. Symmetry operators arise from topological field theories …

A bstract Geometric engineering is a collection of tools developed to establish dictionaries
between local singularities in string theory and (supersymmetric) quantum fields. Extended …

A bstract In many cases the symmetry structure of quantum field theories can be neatly
encoded into their associated symmetry topological field theory (SymTFT), a topological field …
