A fundamental tenet of gauge theory is that physical quantities should be gaugeinvariant. This prompts the question: can gauge symmetries have physical significance? On one hand, the Noether theorems relate conserved charges to symmetries, endowing the latter with physical significance, though this significance is sometimes taken as indirect. But for theories in spatially finite and bounded regions, the standard Noether charges are not gauge-invariant. I here argue that gauge-variance of…

A unified geometric framework for boundary charges and dressings: Non-Abelian theory and matter
Abstract Boundaries in gauge theories are a delicate issue. Arbitrary boundary choices enter the calculation of charges via Noether's second theorem, obstructing the assignment of unambiguous
Soft charges from the geometry of field space
Infinite sets of asymptotic soft-charges were recently shown to be related to new symmetries of the S -matrix, spurring a large amount of research on this and related questions. Notwithstanding, the
Holism as the significance of gauge symmetries
Not all symmetries are on a par. For instance, within Newtonian mechanics, we seem to have a good grasp on the empirical significance of boosts, by applying it to subsystems. This is exemplified by
The quasilocal degrees of freedom of Yang-Mills theory
Gauge theories possess nonlocal features that, in the presence of boundaries, inevitably lead to subtleties. In the $D+1$ formulation of Yang-Mills theories, we employ a generalized Helmholtz

Abstract Local gauge theories are in a complicated relationship with boundaries. Whereas fixing the gauge can often shave off unwanted redundancies, the coupling of different bounded regions requires
Noether's theorems and gauge symmetries
Consideration of the Noether variational problem for any theory whose action is invariant under global and/or local gauge transformations leads to three distinct theorems. These include the familiar
Empirical Consequences of Symmetries
It is widely recognized that ‘global’ symmetries, such as the boost invariance of classical mechanics and special relativity, can give rise to direct empirical counterparts such as the Galileo-ship
Are Gauge Symmetry Transformations Observable?
In a recent paper in this journal, Kosso ([2000]) discussed the observational status of continuous symmetries of physics. While we are in broad agreement with his approach, we disagree with his
Local symmetries and constraints
The general relationship between local symmetries occurring in a Lagrangian formulation of a field theory and the corresponding constraints present in a phase space formulation are studied. First, a
Symmetry and gauge freedom
The classical field theories that underlie the quantum treatments of the electromagnetic, weak, and strong forces share a peculiar feature: specifying the initial state of the field determines the
