Formation and evolution of a 2-brane structure in multidimensional $f(R)$ gravity

Kirill A. Bronnikov, Arkady A. Popov, Sergey G. Rubin

It has been previously shown that multidimensional $f(R)$ gravity {can lead} to a two-brane structure. In this paper, we analyze such a model with a spatially flat 4D de Sitter (dS…
