Toward evading the strong coupling problem in Horndeski genesis
Y. Ageeva, O. Evseev, O. Melichev +1
It is of interest to understand whether or not one can construct a classical field theory description of early cosmology which would be free of the initial singularity and stable t…
Horndeski Genesis: strong coupling and absence thereof
Y. A. Ageeva, O. A. Evseev, O. I. Melichev +1
We consider Genesis in the Horndeski theory as an alternative to or completion of the inflationary scenario. One of the options free of instabilities at all cosmological epochs is…
No static sphericaly symmetric wormholes in Horndeski theory
O. A. Evseev, O. I. Melichev
We consider the Horndeski theory in four-dimensional space-time. We show that this theory does not admit stable, static, spherically symmetric, asymptotically flat, Lorentzian worm…
Instability of Static Semi-Closed Worlds in Generalized Galileon Theories
O. A. Evseev, O. I. Melichev
We consider generalized Galileon theories within general relativity in four-dimensional space-time. We provide the argument showing that the generalized Galileons described by a wi…
