Lecture Notes on Symmetry Reduction via the Dressing Field Method
L. Ravera
These notes - prepared for the conference school "Foundations of General-Relativistic Gauge Field Theory", held on March 17-19, 2026 at the Politecnico di Torino - present introduc…
Dynamical Implementation of the Constraints in Conformal Gravity
L. Andrianopoli, R. D'Auria, G. Grosso +1
We propose a first-order geometric Lagrangian for four-dimensional conformal gravity within the Cartan formulation, which yields, dynamically, the standard constraints on the field…

Laura Andrianopoli, Giuseppe Casale, Lucrezia Ravera +1
We explore the properties of a set of free double-tensor multiplets in supersymmetry, focusing on their behavior within rigid superspace. These multiplets can be obtained fro…
