摘要
We present the bilinear equivalence expression of a (2+1)-dimensional integrable equation of a classical spin system. Based on this, we construct its single-soliton solutions and two-soliton solutions by Hirota's bilinear method. Meanwhile we show the evolution and propagation manners of two-solitons of the spin system graphically.
