摘要：In this talk, we presented a generalized perturbation (n;N-n)-fold Darboux transformation (DT) method and applied it tosome continuous and discrete nonlinear wave models.In particular, we apply the generalized perturbation (1;N-1)-fold DT (i.e. generalized perturbation (n;N-n)-fold Darboux transformation with n=1) to find some explicit higher-order rogue wave solutions in terms of fractional forms of determinantsand alsothe generalized perturbation (2;N-2)-fold DT (i.e. generalized perturbation (n;N-n)-fold Darboux transformation with n=2) to express some explicit localized wave interaction solutions in terms of determinantfor some nonlinear wave systems. We explore some novel localized wave interaction phenomena including the interactions between distinct types of localized waves such as rogue wave, breather and semi-rational soliton. To further illustrate the physical mechanism of these solutions, we explore the dynamical behaviors of some certain rogue wave and localized wave interaction solutions.
