Stability theory of solitary waves in the presence of symmetry. II. (English) Zbl 0711.58013

Summary: Consider an abstract Hamiltonian system which is invariant under a group of operators. We continue to study the effect of the group invariance on the stability of solitary waves [see part I, the authors, ibid. 74, 160- 197 (1987; Zbl 0656.35122)]. Applications are given to bound states and traveling wave solutions of nonlinear wave equations.
