$H^1$-stability of mKdV multi-kinks

Muñoz, Claudio

Journées équations aux dérivées partielles (2011), article no. 8, 16 p.

We describe some recent results concerning the nonlinear $L^2$-stability of multi-solitons of the Korteweg-de Vries equation [4], and $H^1$-stability of multi-kinks of the modified Korteweg-de Vries [49]. The proof of both results is closely linked to stability properties for solitons of the integrable Gardner equation, which have been considered by Martel, Merle and Tsai [41, 40].
