Abstract
We present a construction which associates to a KdV equation the lamplighter group.
In order to establish this relation we use automata and random walks on ultra discrete limits.
It is also related to the L2 Betti numbers introduced by Atiyah which are homotopy
invariants of closed manifolds.
