Interaction of two liquid solitary waves in a trough resonator.

The interaction phenomena of two solitary waves observed by Wu, Keolian, and Rudnick in a trough resonator are analytically analyzed by the perturbative variation method. The coalescence period and the first coalescence time for same-polarity solitary waves as well as the interaction force and the interaction potential are given, which, to a certain extent, can explain the experimental phenomena well. The stable separation between two opposite-polarity solitary waves is explained to be the result of the balance of the soliton interaction force and an equivalent force due to the action of the two end walls on the solitons
