Can Horndeski Genesis be Nonpathological?
Han Gil Choi, Pavel Petrov, Masahide Yamaguchi
We present a minimal setup within the framework of Horndeski gravity that can describe a nonpathological Genesis scenario. Our setup allows for a fully stable transition to the kin…
The primordial non-Gaussianities for non-singular Horndeski cosmologies
Y. Ageeva, M. Kotenko, P. Petrov
We consider a novel Bounce Universe model constructed within the framework of Horndeski gravity. We have analyzed the bispectrum of primordial scalar perturbations and evaluated th…
Non-renormalizable theories and finite formulation of QFT
Y. Ageeva, P. Petrov, M. Shaposhnikov
In this paper, we show how the finite formulation of QFT based on Callan-Symanzik equations can be generalised to the case of non-renormalizable theories. We derive an equation for…
K-inflation: the legitimacy of classical treatment
Y. Ageeva, P. Petrov
In this paper we consider a general theory of k-inlation and find out, that it may be in strong coupling regime. We derive accurate conditions of classical description validity usi…
