A no-go theorem for generalized vector Galileons on flat spacetime
Cedric Deffayet, A. Emir Gumrukcuoglu, Shinji Mukohyama +1
We explore the possibility for generalized electromagnetism on flat spacetime. For a single copy of gauge theory, we show that the Galileon-type generalization of electromag…
The Boulware-Deser mode in Zwei-Dreibein gravity
Máximo Bañados, Cedric Deffayet, Miguel Pino
Massive gravity in three dimensions accepts several different formulations. Recently, the 3-dimensional bigravity dRGT model in first order form, Zwei-Dreibein gravity, was conside…
A formal introduction to Horndeski and Galileon theories and their generalizations
Cedric Deffayet, Daniele A Steer
We review different constructions of Galileon theories in both flat and curved space, and for both single scalar field models as well as multi-field models. Our main emphasis is on…
