| Abstract： |
By virtue of Hirota’s bilinear method and Kadomtsev–Petviashvili hierarchy reduction technique, the general breather, soliton and rational solutions in the (2+1)-dimensional Hirota equation are constructed. These solutions are expressed in terms of Gram determinants and Schur polynomials. The dynamics of these solutions are analyzed in detail. In particular, the interaction between lumps and breathers is discussed, which reveals that the lump can be regarded as a special limit of the breather. Moreover, the semi-rational solutions consisting of lumps, breathers and solitons are also derived, which exhibit rich wave structures. The results provide a deeper understanding of the integrable properties and nonlinear wave phenomena in higher-dimensional systems. |
