关于二维Dirac-Klein-Gordon方程组的代数normal form方法的注记

A remark on the algebraic normal form method applied to the Dirac-Klein-Gordon system in two space dimensions

Masahiro Ikeda, Akihiro Shimomura, Hideaki Sunagawa

摘要:

我们考虑二维空间中的大质量Dirac-Klein-Gordon系统。在非共振质量条件下,证明了在适当的加权索伯列夫空间中,如果初值足够小,则解是渐近自由的。特别地,它证明了DKG系统的狄拉克分量倾向于自由狄拉克方程的解。我们的证明是基于代数范式方法。

英文摘要:

We consider the massive Dirac-Klein-Gordon system in two space dimensions. Under the non-resonace mass condition, we show that the solution is asymptotically free if the initial data are sufficiently small in a suitable weighted Sobolev space. In particular, it turns out that the Dirac component of the DKG system tends to a solution of the free Dirac equation. Our proof is based on the algebraic normal form method.
