报告摘要:
It is well-known that the classical integrable systems adapt solitons, solitons reflect various nice properties of integrable systems. The existence of non-smooth solitons is an non-trivial feature of integrable systems with nonlinear dispersion. In this talk, we shall discuss stability of non-smooth solitons of integrable Novikov-type systems. First, we study integrability of Novikov-type system. Second, orbital stability and asymptotic stability of peaked solitons to an integrable Novikov system are proved. Finally, instability of solutions to the system is investigated.
