Karpman, V. I. Lyapunov approach to the soliton stability in highly dispersive systems. II: KdV-type equations. (English) Zbl 0972.35518 Phys. Lett., A 215, No. 5-6, 257-259 (1996). Summary: The stability of solitons described by fifth order KdV-type equations with arbitrary power nonlinearities is studied by means of the Lyapunov approach. From the results obtained it follows that the solitons are stable at \(p<\)8 where \(p\) is the power of nonlinearity.For Part I, see ibid. 254-256 (1996; Zbl 0972.35519).
