A note on a mimetic scalar-tensor cosmological model | | Yevgeniya Rabochaya
; Sergio Zerbini
; | | Date: |
12 Sep 2015 | | Abstract: | A specific Horndeski scalar-gravity mimetic model is investigated within a
FLWR space-time. The mimetic scalar field is implemented via a Lagrangian
multiplier, and it is shown that the model has equations of motion formally
similar to the original simpler mimetic matter model of
Chamseddine-Mukhanov-Vikman. Several exact solutions describing inflation,
bounces, future time singularities are presented and discussed. | | Source: | arXiv, 1509.3720 | | Services: | Forum | Review | PDF | Favorites | |
