“…it is investigated by Harabetian [14], Matsumura-Nishihara [27], [28], Matsumura-Yoshida [29], [30], and Yoshida [37], [38], [39], [40], [41], [43], that the asymptotic stability and time-decay estimates of various nonlinear waves, such as rarefaction wave, viscous shock wave, viscous contact wave (see also [22], [44]), and multiwave pattern which consists of the rarefaction waves and the viscous contact wave. For the rarefaction problem of the Korteweg-de Vries equation…”
