In this talk, Prof. David Langlois (Laboratoire Astroparticule et Cosmologie, CNRS, Université Paris Diderot, Paris, France) will present theories of modified gravity that contain a single scalar degree of freedom, in particular the very general framework of Degenerate Higher-Order Scalar-Tensor (DHOST) theories, which includes and extends Horndeski and Beyond Horndeski theories. He will then discuss cosmological aspects of these theories and present some results on the perturbations of non-rotating black holes.
