Stability of nonsingular cosmologies in Galileon models with torsion. A no-go theorem for eternal subluminality
S. Mironov, M. Valencia-Villegas
Generic models in Galileons or Horndeski theory do not have cosmological solutions that are free of instabilities and singularities in the entire time of evolution. We extend this…
DPSV trick for spherically symmetric backgrounds
S. Mironov, V. Volkova
We discuss the approach suggested by Deffayet et al. (DPSV) to analysing the linearized perturbations in Horndeski theory in the case of a static, spherically symmetric background.…
Perturbations in Horndeski theory above anisotropic cosmological background
S. Mironov, A. Shtennikova
Considering an anisotropic cosmological background is an interesting and simultaneously challenging problem of theoretical physics, since we not only assume a high degree of anisot…
Quartic Horndeski-Cartan theories in a FLRW universe
S. Mironov, M. Valencia-Villegas
We consider the Quartic Horndeski theory with torsion on a FLRW background in the second order formalism. We show that there is a one parameter family of Quartic Horndeski Cartan L…
