The variable-length stem structures in three-soliton resonance of the Kadomtsev-Petviashvili II equation
Feng Yuan, Jingsong He, Yi Cheng
The stem structure is a localized feature that arises during high-order soliton interactions, connecting the vertices of two V-shaped waveforms. The interaction of resonant 3-solit…

Localized stem structures in quasi-resonant solutions of the Kadomtsev-Petviashvili equation
Feng Yuan, Jingsong He, Yi Cheng
When the phase shift of X-shaped solutions before and after interaction is finite but approaches infinity, the vertices of the two V-shaped structures become separated due to the p…

Localized stem structures in soliton reconnection of the asymmetric Nizhnik-Novikov-Veselov system
Feng Yuan, Jingsong He, Yi Cheng
The reconnection processes of 3-solitons with 2-resonance can produce distinct local structures that initially connect two pairs of V-shaped branches, then disappear, and later re-…
