Finite-time future singularities in modified Gauss-Bonnet and gravity and singularity avoidance

Kazuharu Bamba, Sergei D. Odintsov, Lorenzo Sebastiani +1

We study all four types of finite-time future singularities emerging in late-time accelerating (effective quintessence/phantom) era from -gravity, where and $…

Functional Determinants in Higher Derivative Lagrangian Theories

Roberto Di Criscienzo, Sergio Zerbini

Motivated by the considerable success of alternative theories of gravity, we consider the toy model of a higher derivative Lagrangian theory, namely the Pais-Uhlenbeck oscillator s…

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-…
