Re: Dynamical Systems and Expansion-Contraction

Following Coley (1999), especially important exact self-similar
solutions are:

1) Minskowski space (M) such that:
1a) z = tDt + xDx + yDy + zDz
2) Friedmann-Roberson-Walker (FRW) models:
2a) z = tDt + (1 - 2/(3g))(2xDx + yDy + zDz)
3) Kasner (vacuum) (K):
3a) z = tDt + (1-p1)xDx + (1-p2)yDy + (1-p3)zDz.c

where Dx is the partial derivative with respect to x, etc., g isn't the
metric in (2a), and sum pi is 1 which is also sum pi^2.

I'll try to list the respective metrics next time.
