The complete action for de Sitter pure supergravity
Nicolas Boulanger, Vasileios A. Letsios, Sylvain Thomée
Supergravity theories in de Sitter spacetime are known to be very constrained, and rather unnatural within String/M Theory. We revisit the seminal paper by Pilch, van Nieuwenhuizen…
8D conformal gravity with Einstein sector, and its relation to the Q-curvature
Nicolas Boulanger, Davide Rovere
We first streamline the construction of the unique six-dimensional conformal gravity action found by Lü, Pang and Pope, that admits Einstein metrics as solutions to the field equat…
Kinematical Lie algebras and symplectic symmetric spaces I: Lie algebraic aspects
Pierre Bieliavsky, Nicolas Boulanger
We generalize the notion of kinematical Lie algebra introduced in physics for the classification of the various possible relativity algebras an isotropic spacetime can accommodate.…
A note on partially massless supergravity
Nicolas Boulanger, Guillaume Lhost, Sylvain Thomée
We analyse the couplings of a partially massless spin-2 field with a doublet of massless, real spin-3/2 fields. In the flat limit, this spectrum coincides with the spectrum of ${\c…
