Abstract

We describe all solutions of the Burgers equation of analytic complexity not exceeding . It turns out that all such solutions fall into four families of dimensions not exceeding that are represented by elementary functions. An example of a family of solutions of the Burgers equation of complexity is given. A similar problem is also solved for the Hopf equation. It turns out that all solutions to the Hopf equation of complexity form a two-parameter family of fractional-linear functions which coincides with one of the families of solutions of the Burgers equation.

Burgers和Hopf方程的简单解

我们描述了解析复杂度不超过的Burgers方程的所有解。事实证明，所有这些解都属于四个维族，不超过这些维族是由初等函数表示的。给出了复杂的Burgers方程的一类解的例子。对于Hopf方程也解决了一个类似的问题。结果表明，复杂Hopf方程的所有解都形成一个双参数分数线性函数族，这与Burgers方程的一个解族相吻合。
