摘要
考虑了径向对称非线性扩散方程的条件Lie-Bcklund对称和符号不变量.允许二阶条件Lie-Bcklund对称和一阶Hamilton-Jacobi型符号不变量的方程被确定给出,并由对称约化得到了方程的不变解.
The conditional Lie-Bcklund symmetries and sign-invariants of the radially symmetric non-linear diffusion equations were considered.The equations,which admitted of second-order conditional Lie-Bcklund symmetries and first-order Hamilton-Jacobi sign-invariants,were obatined and the corresponding invariant solutions to the resulting equations were also obtained due to symmetry reductions.
