Stability of the de-Sitter spacetime. The anisotropic case

Przemysław Bieniek, Jan Chojnacki, Jan H. Kwapisz +1

We elaborate on the cosmological implications of the recently established non-perturbative O(D,D)-symmetric approach. Following the α′-complete Friedmann equations, we provide…

Non-linear stability of α′-corrected Friedmann equations

Heliudson Bernardo, Jan Chojnacki, Vincent Comeau

We study the non-linear stability of fixed-point solutions to the α′-exact equations from O(d,d) invariant cosmology, with and without matter perturbations. Previous non-linear…

Stability of the non-perturbative O(D,D) de-Sitter spacetime. The isotropic case

Przemysław Bieniek, Jan Chojnacki, Jan H. Kwapisz +1

The existence of de-Sitter solutions and their stability within string theory became, in recent years, one of the central research questions within the string theory community. The…
