Talk Title |
Spiky Mixmaster dynamics |
|
Abstract |
It was thought that the general dynamics near a singularity is mildly inhomogeneous. i.e. spatial derivative terms are much smaller than time derivative terms. Recent evidence of formation of spiky structures suggests otherwise. Exact solutions for the spikes have been found by applying a solution-generating transformation to known solutions. Numerical simulations indicate that general solutions converge to the spike solutions near a singularity, and that the spikes recur. |
