“…There are many results concerning the existence and time-decay properties of solutions, the stability of nonlinear waves (that is, rarefaction waves, shock waves (travelling wave), viscous contact waves and and multiwave pattern of rarefaction waves and viscous contact waves) and the other mathematical structure of the models (1.2)-(1.10) (and, (1.15) and (1.16) in Remark 1.3) (for the related works, see Amick-Bona-Schonbek [2], Andreiev-Egorova-Lange-Teschl [3], Benjamin-Bona-Mahony [4], Bona-Schonbek [5], Bona-Rajopadhye-Schonbek [6], Duan-Fan-Kim-Xie [7], Duan-Zhao [8], Egorova-Grunert-Teschl [9], Egorova-Teschl [10], Harabetian [11], Hattori-Nishihara [13], Il'in-Oleȋnik [15], Kondo-Webler [17]- [20], Matsumura-Nishihara [24]- [26], Matsumura-Yoshida [27], [28], Mei [29], [30], Mei-Schmeiser [31], Naumkin [32], Nishihara-Rajopadhye [33], Osher-Ralston [34], Peregrine [35], Rajopadhye [36], Rashindinia-Nikan-Khoddam [37], Ruan-Gao-Chen [38], Wang [39], Wang-Zhu [40], Xu-Li [41], Yin-Zhao-Kim [42], Yoshida [43]- [53], Zhao-Xuan [54] and so on).…”
