Asymptotic cosmological solutions: orthogonal Bianchi type-II models

The time evolution of the orthogonal spatially homogeneous Bianchi type-II models is analaysed by applying qualitative techniques to the reduced and regularised differential system of Rosquist and Jantzen [1988, Phys. Rep. 166, 89]. This enables us to obtain the asymptotic behaviour of solutions near the initial singularity and in the distant future. A global picture emerges in which the general orthogonal type-II solution is shown to be spiralling about the non-LRS solution found by previous workers. (author)
