Abstract | We study solitary waves in the cylindrical Kadomtsev–Petviashvili equation designated to media with positive dispersion (the cKP1 equation). By means of the Darboux-Matveev transform, we derive exact solutions that describe two-dimensional solitary waves (lumps), lump chains, and their interactions. One of the obtained solutions describes the modulation instability of outgoing ring solitons and their disintegration onto a number of lumps. We also derive solutions describing decaying lumps and lump chains of a complex spatial structure—ripplons. Then, we study normal and anomalous (resonant) interactions of lump chains with each other and with ring solitons. The results obtained agree with |
