Multidimensional gravity with higher derivatives and inflation
Júlio C. Fabris, Arkady A. Popov, Sergey G. Rubin
We elaborate on the inflationary model starting from multidimensional Lagrangian and gravity with second-order curvature terms. The effective scalar field is related to the Ricci s…
Propagation of Gravitational Waves in Chern-Simons Axion Einstein Gravity
Shin'ichi Nojiri, S. D. Odintsov, V. K. Oikonomou +1
In this paper we shall investigate the propagation of gravitational waves in a flat Friedman-Robertson-Walker background, in the context of a string motivated corrected Einstein gr…
Evolution of sub-spaces at high and low energies
Arkady A. Popov, Sergey G. Rubin
The evolution of sub-spaces in the framework of gravity with higher derivatives is studied. Numerical solutions to exact differential equations are found. It is shown that the init…
