Convergence to equilibrium due to collisions with external particles
2018, v.24, №2, 197-227
We consider a class of ``most non ergodic'' particle systems and prove
that for most of them ergodicity appears if only one particle of $N$ has
contact with external world, that is this particle collides with
external particles in random time moments.
