One-loop effective action for non-local modified Gauss-Bonnet gravity in de Sitter space
Guido Cognola, Emilio Elizalde, Shin'ichi Nojiri +2
We discuss the classical and quantum properties of non-local modified Gauss-Bonnet gravity in de Sitter space, using its equivalent representation via string-inspired local scalar-…

Effective gravity formulation that avoids singularities in quantum FRW cosmologies
Jaume Haro, Emilio Elizalde
Assuming that time exists, a new, effective formulation of gravity is introduced, which lies in between the Wheeler-DeWitt approach and ordinary QFT. Remarkably, the Penrose-Hawkin…
