Higher Dressing and Shift-Invariance in 4D Topological BF Theory
J. François, L. Ravera
A characteristic feature of topological field theories is the absence of local propagating degrees of freedom. In four-dimensional BF theory with cosmological term, we make this fe…
Toward Manifest Relationality in Transformers via Symmetry Reduction
J. François, L. Ravera
Transformer models contain substantial internal redundancy arising from coordinate-dependent representations and continuous symmetries, in model space and in head space, respective…
Raising galaxy rotation curves via dressing
J. François, L. Ravera
We present a manifestly diffeomorphism-invariant simple model of galaxy dynamics obtained by applying the Dressing Field Method (DFM) to a general-relativistic system comprising th…
Reassessing the foundations of Metric-Affine Gravity
J. François, L. Ravera
We reassess foundational aspects of Metric-Affine Gravity (MAG) in light of the Dressing Field Method, a tool allowing to systematically build gauge-invariant field variables. To g…
Off-shell supersymmetry via manifest invariance
J. François, L. Ravera
A fundamental challenge in supersymmetric field theory is that supersymmetry transformations on field variables generally form an algebra only on-shell, i.e. upon imposing the fiel…
Relational Supersymmetry via the Dressing Field Method and Matter-Interaction Supergeometric Framework
J. François, L. Ravera
Relationality is the paradigmatic conceptual core of general-relativistic gauge field theory. It can be made manifest via the Dressing Field Method (DFM) of symmetry reduction, a s…
Relational bundle geometric formulation of non-relativistic quantum mechanics
J. François, L. Ravera
We present a bundle geometric formulation of non-relativistic many-particles Quantum Mechanics. A wave function is seen to be a -valued cocyclic tensorial 0-form on con…
Dressing fields for supersymmetry: The cases of the Rarita-Schwinger and gravitino fields
J. François, L. Ravera
In this paper we argue that the gauge-fixing conditions typically used to extract the (off-shell) degrees of freedom of the Rarita-Schwinger spinor-vector and gravitino, respective…
On the Meaning of Local Symmetries: Epistemic-Ontological Dialectics
Jordan François, Lucrezia Ravera
We propose our account of the meaning of local symmetries. We argue that the general covariance principle and gauge principle both are principles of democratic epistemic access to…
Note on the group of vertical diffeomorphisms of a principal bundle, and its relation to the Frölicher-Nijenhuis bracket
Jordan François
The group of vertical diffeomorphisms of a principal bundle forms the generalised action Lie groupoid associated to the bundle. The former is generated by the group of maps with va…
