摘要
An existence theory for small amplitude solitary waves with surface tension effects included is developed for large values of the surface tension parameter (β > 1 3). Using ideas of Beale, the Nash-Moser implicit function theorem is applied to justify the well-known approximation of Korteweg and deVries. Some of the recent results of Amick and Kirchgässner are thereby achieved more directly and additional insight obtained for the open case β < 1 3. © 1991.
