Painleve 性质和无限的对称(2+1 )-dimensionalhigher-order Broer—Kaup (HBK ) 系统在这篇论文被学习。用修改直接方法,我们导出一般对称组的定理到(2+1 ) 维的 HBK 系统。基于我们的定理,答案的一些新形式被获得。我们也发现守恒定律的无限的数字(2+1 ) 维的 HBK 系统。
Painleve property and infinite symmetries of the (2+1)-dimensional higher-order Broer-Kaup (HBK) system are studied in this paper. Using the modified direct method, we derive the theorem of general symmetry gro.ups to (2+1)-dimensional HBK system. Based on our theorem, some new forms of solutions are obtained. We also find infinite number of conservation laws of the (2+1)-dimensional HBK system.
