The Proof of the Boltzmann-Sinai Ergodic Hypothesis for Typical
Hard Disk Systems
(467K, Postscript)
ABSTRACT. We consider the system of $N$ ($\ge2$) hard disks of masses
$m_1,\dots,m_N$ and radius $r$ in the flat unit torus $\Bbb T^2$.
We prove the ergodicity (actually, the B-mixing property) of such
systems for almost every selection $(m_1,\dots,m_N;r)$ of the outer
geometric parameters.
