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 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, normally interacting lump chains degenerate into anomalously interacting lump chains with the same parameters as the first path. Secondly, the anomalously lump waves can

be derived from the 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|.
