论文摘要
在本文中，我们研究了扩展$ k（m，n，p）$方程的对称性$$ u_t = a（u^p）_ {xxxxx} + b（u^n）_ {xxx} + c（u^m）对于$ a \ neq 0 $和$ p \ neq 1，-4 $，此方程没有大于五的订单的通用对称性，因此无法对称。
In the present paper we study symmetries of extended $K(m,n,p)$ equation $$ u_t=a(u^p)_{xxxxx}+b(u^n)_{xxx} + c(u^m)_{x} + f(u), $$ where $a,b,c$ are arbitrary real constants and $m,n,p$ are arbitrary integers, and prove that for $a\neq 0$ and $p\neq 1,-4$ this equation has no generalized symmetries of order greater than five and hence is not symmetry integrable.
