The Generic Expansion in Analytic Modified Gravity
Dimitrios Trachilis
In this Thesis, we treat the problem of the existence of generic perturbations of the regular and singular state in higher-order gravity in cases of vacuum and radiation models tha…

Generic regular universes in higher order gravity theories
Spiros Cotsakis, Dimitrios Trachilis, Antonios Tsokaros
We review recent results on the Cauchy-Kowalevsky structure of theories with higher derivatives in vacuum. We prove genericity of regularity of solutions under the assumption of an…
