Oscillatory Behaviour in Homogeneous String Cosmology Models

Some spatially homogeneous Bianchi type I cosmological models filled with homogeneous electric'' $p$-form fields are shown to mimic the never-ending oscillatory behaviour of generic string cosmologies established recently. The validity of the Kasner-free-flights plus collisions-on-potential-walls’’ picture is also illustrated in the case of known, non-chaotic, superstring solutions.
