AI 中文摘要
利用点对称性和奇异性分析方法检测(1+3)维Kudryashov-Sinelshchikov方程的可积性。对称性大多指向存在具有大多任意函数的无限维李代数。通过在一般对称向量中考虑这些任意函数来启动约化过程。对于某些函数，得到了一般母方程的平凡解，而对于一些函数，约化没有产生明确结果。最后，列出了一个任意函数的积极结果，用奇异性分析方法研究Painleve性质。所得偏微分方程恰好是一个四阶方程，其对Painleve性质的认可暗示了Kudryashov-Sinelshchikov方程在一般情况下的可积性。
英文摘要
The integrability of the Kudryashov-Sinelshchikov equation in (1+3) dimension is detected using its point symmetries and the Singularity analysis method. The symmetries mostly points to the existence of infinite-dimensional Lie algebra with the presence of mostly arbitrary functions. The reduction process is initiated by considering these arbitrary functions in the general symmetry vectors. For certain functions, trivial solutions for the general parent equation is obtained whereas for some of the functions, the reductions does not yield an unmitigated result. Finally, a positive result is listed for one of the arbitrary function, for which the singularity analysis method is employed to study the Painleve property. The resultant PDE happens to be a fourth-order equation and its approval of the Painleve property hints at the integrability of the Kudryashov- Sinelshchikov equation in the general case.
