Bianchi \(A\) cosmological models as the simplest dynamical systems in \({\mathbb{R}}^4\)
The authors have studied the method of reducing Bianchi \(A\) cosmological models to dynamical systems of 4-dimension by solving Einstein equations in vacuum and using the correspondence with Hamiltonian system in 3-dimensional phase space with zero energy.
