阻尼Korteweg-de Vries型方程的指数衰减率

Exponential Decay Rates for the Damped Korteweg-de Vries Type Equation

M. M. Cavalcanti, V. N. Domingos Cavalcanti, F. Natali

摘要:

建立了整条实直线上具有局部阻尼的Korteweg-de Vries方程的$L^2-$范数的指数衰减率。另外,利用经典的方法,我们确定了具有阻尼的Korteweg-de Vries方程的解在整个区域上的$H^1-$范数,对于任意的初值,该解不具有衰减性.

英文摘要:

The exponential decay rate of $L^2-$norm related to the Korteweg-de Vries equation with localized damping posed on whole real line will be established. In addition, by using classical arguments we determine the $H^1-$norm of the solution associated to Korteweg-de Vries equation with damping in whole domain, can not have a decay property for an arbitrary initial data.
