Coupling of radial and non-radial oscillations of Neutron stars
Andrea Passamonti, Marco Bruni, Leonardo Gualtieri +1
This is a progress report on our study of the coupling of first-order radial and non-radial relativistic perturbations of a static spherical star. Our goal is to investigate the ef…

No consistent cross-interactions for a collection of massless spin-2 fields
Nicolas Boulanger, Thibault Damour, Leonardo Gualtieri +1
We report a no-go theorem excluding consistent cross-couplings for a collection of massless, spin-2 fields described, in the free limit, by the sum of Pauli-Fierz actions (one for…

Harmonic Analysis and Superconformal Gauge Theories in Three Dimensions from AdS/CFT Correspondence
Leonardo Gualtieri
In this thesis I review various aspects of the AdS_4/CFT_3 correspondence, where AdS_4 supergravity arises from compactification of M-theory on a coset space G/H and preserves N<8…
