Soliton asymptotics of the Cauchy problem solution for the Toda lattice. (English) Zbl 0872.35107

Summary: The solution of the Cauchy problem for the Toda lattice with step-like initial data is shown to split into an infinite series of solitons when time tends to infinity. An exact asymptotic formula for such solutions is obtained.
