Cosmological models in modified gravity theories with extended nonminimal derivative couplings
Tiberiu Harko, Francisco S. N. Lobo, Emmanuel N. Saridakis +1
We construct gravitational modifications that go beyond Horndeski, namely theories with extended nonminimal derivative couplings, in which the coefficient functions depend not only…
Bi-scalar modified gravity and cosmology with conformal invariance
Emmanuel N. Saridakis, Minas Tsoukalas
We investigate the cosmological applications of a bi-scalar modified gravity that exhibits partial conformal invariance, which could become full conformal invariance in the absence…
Cosmology in new gravitational scalar-tensor theories
Emmanuel N. Saridakis, Minas Tsoukalas
We investigate the cosmological applications of new gravitational scalar-tensor theories, which are novel modifications of gravity possessing 2+2 propagating degrees of freedom, ar…
