广义位势Burgers方程的等价广群

Equivalence groupoid of generalized potential Burgers equations

Oleksandr A. Pocheketa

摘要:

找到了一类$(1+1)$维二阶发展方程的等价广群,称之为广义位势Burgers方程.这一类是通过潜在的两类变系数广义Burgers方程。它的等价广群具有复杂的结构,通过将整个类划分为三个规范化子类来描述,使得不同子类的方程之间不存在点变换。对于每一个子类,我们构造一个适当类型的等价群。

英文摘要:

We find the equivalence groupoid of a~class of $(1+1)$-dimensional second-order evolution equations, which are called generalized potential Burgers equations. This class is related via potentialization with two classes of variable-coefficient generalized Burgers equations. Its equivalence groupoid is of complicated structure and is described via partitioning the entire class into three normalized subclasses such that there are no point transformations between equations from different subclasses. For each of these subclasses we construct its equivalence group of an appropriate kind.
