Auxiliary fields representation for modified gravity models
Davi C. Rodrigues, Filipe de O. Salles, Ilya L. Shapiro +1
We consider tensor-multiscalar representations for several types of modified gravity actions. The first example is the theory with the action representing an arbitrary smooth funct…
