Analytic integrability of the Bianchi class A cosmological models with O~ 1< < 1
Ferragut, Antoni; Llibre, Jaume; Pantazi, Chara Elsevier (2013-03)Many works study the integrability of the Bianchi class A cosmologies with k = 1, where k is the ratio between the pressure and the energy density of the matter. Here we characterize the analytic integrability of the Bianchi ... -
On the absence of analytic integrability of the Bianchi Class B cosmological models
Ferragut, Antoni; Llibre, Jaume; Pantazi, Chara American Institute of Physics (AIP) (2013-02-15)We follow Bogoyavlensky's approach to deal with Bianchi class B cosmological models. We characterize the analytic integrability of such systems.
