摘要
考虑一个广义多孔介质方程的势对称群,证明了存在某一类特定的多孔介质方程允许一定势对称群,并在此基础上得出不变解.
Discussed the potential symmetries of one generalized porous medium equations. It was shown that there are some generalized porous medium equations which admit certain types of nonlocal symmetries. As a result, invariant solutions was obtained.
