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 …

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 …

Gauge symmetries play a central role, both in the mathematical foundations as well as the
conceptual construction of modern (particle) physics theories. However, it is yet unclear …

A bstract In this note, we consider how the bundle geometry of field space interplays with the
covariant phase space methods so as to allow to write results of some generality on the …

We provide an elegant homological construction of the extended phase space for linear
Yang–Mills theory on an oriented and time-oriented Lorentzian manifold M with a time-like …

To systematically answer the generalized Kretschmann objection, I propose a mean to make
operational a criterion widely recognized as allowing one to decide whether the gauge …

A bstract We take advantage of the principal bundle geometry of the space of connections to
obtain general results on the presymplectic structure of two classes of (pure) gauge theories …

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 …

Taking manifest invariance under both gauge symmetry and diffeomorphisms as a guiding
principle physical objects are constructed for Yang-Mills-Higgs theory coupled to quantum …

In this paper, we revisit the Dressing Field Method (DFM) in the context of Quantum (Gauge)
Field Theories (QFT). In order to adapt this method to the functional path integral formalism …
