Starting with a gentle approach to the Alday–Gaiotto–Tachikawa (AGT) correspondence
from its 6d origin, these notes provide a wide (albeit shallow) survey of the literature on …

A bstract We discuss the origin of the choice of global structure for six dimensional (2, 0)
theories and their compactifications in terms of their realization from IIB string theory on ALE …

A bstract Spatial compactification on\({\mathrm {\mathbb {R}}}^ 3\times {\mathbb {S}} _L^ 1\)
at small\({\mathbb {S}}^ 1\)-size L often leads to a calculable vacuum structure, where …

We classify the global one-form symmetries for non-Lagrangian $\mathcal {N}= 3$ SCFTs
that arise by the action of $ S $-fold projections on D3-branes. Such a classification is …

We classify the phases of N= 2 elliptic models in terms of their global properties ie the
spectrum of line operators. We show the agreement between the field theory and the M …

A bstract The additional data necessary to univocally fix the gauge group for a given algebra
are represented by the same charge lattices of mutually local Wilson and't Hooft lines for …

In this paper, we determine the charge lattice of mutually local Wilson and't Hooft line
operators for class S theories living on M5-branes wrapped on compact Riemann surfaces …

We demonstrate explicitly that the vacuum expectation values (vevs) of BPS line operators in
4d N= 2 super Yang–Mills theory compactified on a circle, computed by localization …

We address the problem of giving an algebraic description of global properties of gauge
theories. Our main purpose is to show that, starting with a gauge theory based on a given …

The additional data necessary to univocally fix the gauge group for a given algebra are
represented by the same charge lattices of mutually local Wilson and't Hooft lines for both 4d …
