通过符号计算,从方程的广田双线性形式中寻找正二次函数,得到了(3+ 1)维非线性发展方程的一些集中解。二次函数包含六个自由参数,其中四个满足两个决定性条件,保证解析性和合理的本地化的解决方案,而其他的是免费的。然后,利用正二次函数和指数函数相结合的方法,在一定条件下得到了块解与条纹孤子相互作用的解。进一步地,我们将此方法推广到正二次函数和双曲余弦函数的结合,得到了更一般的解。在此基础上,导出了集中解与一对共振条形孤子相互作用的解,并在一定条件下分析了其渐近性质。最后,这些解决方案的动态特性显示在图中通过选择参数的值。
With symbolic computation, some lump solutions are presented to a (3+ 1)-dimensional nonlinear evolution equation by searching the positive quadratic function from the Hirota bilinear form of equation. The quadratic function contains six free parameters, four of which satisfy two determinant conditions guaranteeing analyticity and rational localization of the solutions, while the others are free. Then, by combining positive quadratic function with exponential function, the interaction solutions between lump solutions and the stripe solitons are presented on the basis of some conditions. Furthermore, we extend this method to obtain more general solutions by combining of positive quadratic function and hyperbolic cosine function. Thus the interaction solutions between lump solutions and a pair of resonance stripe solitons are derived and asymptotic property of the interaction solutions are analyzed under some specific conditions. Finally, the dynamic properties of these solutions are shown in figures by choosing the values of the parameters.
