【報告題目】Soliton molecules, multi-lumps, multi-breathers and hybrid solutions in (2+1)-dimensional Korteweg-de Vries-Sawada-Kotera-Ramani equation

【報 告 人】任博教授,浙江工業大學

【報告摘要】The (2+1)-dimensional Korteweg-de Vries-Sawada-Kotera-Ramani (KdVSKR) equation is proposed by extending one dimension of the (1+1)-dimensional KdVSKR equation. The bilinear form of the (2+1)-dimensional KdVSKR equation is obtained by the independent transformation. The multi-solitons are obtained by solving the Hirota bilinear form of the (2+1)-dimensional KdVSKR equation. By using the long wave limit method, the multi-order lumps are derived. Soliton molecules of the KdVSKR equation are given by means of the velocity resonance mechanism. Multi-breather solutions are derived by selecting the complex conjugate relations in the parameters. The relative positions for the maximum amplitudes of the multi-breathers can adjust with different values of the phases. The phases of the multi-soliton solutions play an important effect in certain phenomena. In the meanwhile, the interactions between a soliton molecule and one-order breather, and between a soliton molecule and one-order lump of the KdVSKR equation are analyzed. These interactions are studied both the analytical and graphical ways.

【報告題目】Decompositions and linear superpositions of B-type Kadomtsev-Petviashvili equations

【報 告 人】樓森岳教授,寧波大學 

【報告摘要】The existence of decomposition solutions of the well-known nonlinear BKP hierarchyis explored. It is shown that these decompositions provide simple and interesting relationships between classical integrable systems and the BKP hierarchy Further, some special decomposition solutions  display a rare property: they can be linearly superposed. With the emphasis on the case of the fifth BKP equation, the structure characteristic having linear superposition solutions is analyzed.Finally, we obtain similar superposed solutions in the dispersionless BKP hierarchy.
