# Future asymptotic behaviour of tilted Bianchi models of type IV and VIIh

@article{Hervik2005FutureAB, title={Future asymptotic behaviour of tilted Bianchi models of type IV and VIIh}, author={Sigbj{\o}rn Hervik and Robert van den Hoogen and A. A. Coley}, journal={Classical and Quantum Gravity}, year={2005}, volume={22}, pages={607-633} }

Using dynamical systems theory and a detailed numerical analysis, the late-time behaviour of tilting perfect fluid Bianchi models of types IV and VIIh is investigated. In particular, vacuum plane-wave spacetimes are studied and the important result that the only future attracting equilibrium points for non-inflationary fluids are the plane-wave solutions in Bianchi type VIIh models, is discussed. A tiny region of parameter space (the loophole) in the Bianchi type IV model is shown to contain a…
