微分约束与非线性扩散方程的精确解

Differential constraints and exact solutions of nonlinear diffusion equations

Oleg V. Kaptsov, Igor V. Verevkin

摘要:

利用微分约束得到了非线性扩散方程的显式解。某些线性确定方程的参数被用来找到这样的微分约束。他们推广了用于寻找经典李对称性的决定方程。

英文摘要:

The differential constraints are applied to obtain explicit solutions of nonlinear diffusion equations. Certain linear determining equations with parameters are used to find such differential constraints. They generalize the determining equations used in the search for classical Lie symmetries.
