“好”Boussinesq方程的Miura变换

Miura transformation for the "good'' Boussinesq equation

Christophe Charlier, Jonatan Lenells

AI总结:

本文证明了“好”Boussinesq方程存在类似KdV情形的Miura型变换,并借助底层Riemann–Hilbert问题的对应关系完成构造。

摘要:

众所周知,mKdV方程的每个解通过Miura变换都能生成KdV方程的一个解。本文证明,对于“好”Boussinesq方程也存在类似的Miura型变换。该变换将一个二阶方程的解映射为四阶Boussinesq方程的解。正如mKdV与KdV的情形一样,这种对应关系也存在于底层的Riemann–Hilbert问题层面,而这实际上正是我们构造这一新变换的方式。

英文摘要:

It is well-known that each solution of the mKdV equation gives rise, via the Miura transformation, to a solution of the KdV equation. In this work, we show that a similar Miura-type transformation exists also for the ``good'' Boussinesq equation. This transformation maps solutions of a second-order equation to solutions of the fourth-order Boussinesq equation. Just like in the case of mKdV and KdV, the correspondence exists also at the level of the underlying Riemann--Hilbert problems and this is in fact how we construct the new transformation.
