Talking About Singularities
Spiros Cotsakis
We discuss some aspects of recent research as well as more general issues about motivation, useful methods and open problems in the field of cosmological singularities. In particul…
Asymptotics of flat, radiation universes in quadratic gravity
Spiros Cotsakis, Antonios Tsokaros
We consider the asymptotics of flat, radiation-dominated isotropic universes in four-dimensional theories with quadratic curvature corrections which may arise when contributions re…
Flat, radiation universes with quadratic corrections and asymptotic analysis
Spiros Cotsakis, Antonios Tsokaros
It was shown long ago by T. V. Ruzmaikina and A. A. Ruzmaikin that within the framework of a homogeneous and isotropic cosmological model quadratic corrections of the gravitational…
Braneworld cosmological singularities
Ignatios Antoniadis, Spiros Cotsakis, Ifigeneia Klaoudatou
The purpose of this brief report is to present some results of our on-going project on the asymptotic behaviour of braneworld-type solutions on approach to their possible finite `t…
