Nearly Starobinsky inflation from modified gravity
L. Sebastiani, G. Cognola, R. Myrzakulov +2
We study inflation induced by (power-low) scalar curvature corrections to General Relativity. The class of inflationary scalar potentials , general paramete…

Vacuum energy fluctuations, the induced cosmological constant and cosmological reconstruction in non-minimal modified gravity models
G. Cognola, E. Elizalde, S. Nojiri +1
The one-loop effective action for non-minimal scalar modified gravity on de Sitter background with a constant scalar field is found. The corresponding induced cosmological constant…
