# Generalized Galileon duality

@article{Rham2014GeneralizedGD, title={Generalized Galileon duality}, author={Claudia de Rham and Luke Keltner and Andrew J. Tolley}, journal={Physical Review D}, year={2014}, volume={90}, pages={024050} }

We generalize the Galileon duality to any single scalar field Lagrangian coupled locally to any matter field. Under the duality, a generalized Galileon maps into another generalized Galileon via a one-parameter group of transformations, with only a simple modification of the Lagrangian functions. We find a special class of generalized Galileons for which the duality is a symmetry of the action. We further extend the duality to the case of vector fields and give the dual formulations of the…
