有限区域上一类Korteweg-de Vries方程Initial-Boundary-Value Problem的整体适定性和渐近性

Global Well-posedness and Asymptotic Behavior of a Class of Initial-Boundary-Value Problem of the Korteweg-de Vries Equation on a Finite Domain

Ivonne Rivas, Muhammad Usman, Bing-Yu Zhang

摘要:

本文研究了有限区间上Korteweg- de Vries方程的一类具有非齐次边界条件的初边值问题。已知IBVP是局部适定的,但其全局$L^2 $先验估计不可用,因此不清楚其解是否全局存在或在有限时间内爆破。本文证明了,只要解的初值和边界数据都很小时,解是全局存在的,而且,如果解的边界数据是指数衰减的,则解是指数衰减的

英文摘要:

In this paper, we study a class of initial boundary value problem (IBVP) of the Korteweg- de Vries equation posed on a finite interval with nonhomogeneous boundary conditions. The IBVP is known to be locally well-posed, but its global $L^2 $ a priori estimate is not available and therefore it is not clear whether its solutions exist globally or blow up in finite time. It is shown in this paper that the solutions exist globally as long as their initial value and the associated boundary data are small, and moreover, those solutions decay exponentially if their boundary data decay exponentially
