摘要: On the bases of N-soliton solutions of Hirota’s bilinear method, anomalously interacting lump patterns of (2+1)-dimensional BKP equation can be generated through normally interacting lump chains by two different paths. In the first path, through tending the periods of M normally lump chains with close velocities to infinity, M(M + 1)/2 anomalously interacting lumps are obtained directly. In the second path, there are two steps to generate lumpwaves. Firstly, M normally interacting lump chains degenerate into M anomalously interacting lump chains with the same parameters as the first path. Secondly, the anomalously lump waves can

be derived from the M anomalously interacting lump chains when the period tends to infinity. Moreover, the distance between anomalously interacting lump chains varies with time proportional to ln |t|.
