Helge Krueger and Gerald Teschl Stability of the Periodic Toda Lattice in the Soliton Region (80K, LaTeX2e) ABSTRACT. We apply the method of nonlinear steepest descent to compute the long-time asymptotics of the periodic (and slightly more generally of the quasi-periodic finite-gap) Toda lattice for decaying initial data in the soliton region. In addition, we show how to reduce the problem in the remaining region to the known case without solitons.
