具有耗散非线性项的Klein-Gordon方程组小解衰减的注记

Remarks on decay of small solutions to systems of Klein-Gordon equations with dissipative nonlinearities

Donghyun Kim, Hideaki Sunagawa

摘要:

考虑一维空间中三次非线性Klein-Gordon方程组的Cauchy问题。在适当的非线性结构条件下,我们将证明小振幅解在$L^p$,$2\le p \le \infty$意义下比自由演化获得额外的对数衰减.

英文摘要:

We consider the Cauchy problem for systems of cubic nonlinear Klein-Gordon equations in one space dimension. Under a suitable structural condition on the nonlinearity, we will show that the small amplitude solution gains an additional logarithmic decay in comparison with the free evolution in the sense of $L^p$, $2\le p \le \infty$.
