摘要

The (2 + 1)-dimensional Ito equation is extended to a general form including some nonintegrable effects via introducing generalized bilinear operators.It is pointed out that the nonintegrable (2 + 1)-dimensional Ito equation contains lump solutions and interaction solutions between lump and stripe solitons.The result shows that the lump soliton will be swallowed or arisen by a stripe soliton in a fixed time.Furthermore,by the interaction between a lump and a paired resonant stripe soliton,the lump will be transformed to an instanton or a rogue wave.
