摘要:

给出了一类基本发展微分方程边值问题的Lie意义下的不变性的定义。本文提出了一个在一类由任意元素参数化的边值问题上的群分类问题,并给出了一个求解算法。对半无限体热传导数学模型中的一类(1+1)维非线性热方程边值问题进行了群分类。一个例子的不变的解决方案的BVP从所研究的类。

英文摘要:

A definition of invariance in Lie's sense for a boundary value problem (BVP) with the basic evolution differential equations is proposed. A problem of group classification at a wide class of BVPs parameterized by arbitrary elements is formulated and an algorithm for its solution is also proposed. The group classification of a class of BVPs for an (1+1)--dimensional nonlinear heat equation arising from mathematical modeling of heat conduction in semi-infinite body is carried out. An example of invariant solution of a BVP from the class under study is presented.
