發(fā)布時間:2018-10-17 18:37
【摘要】:本文研究了如下的分數(shù)次Benjαmin-Bonα-Mαhony(BBM)方程的柯西問題的解的漸進行為(?)tu +(?)xu + u(?)xu + Dα(?)tu =0,其中α0,Dα定義如下(?)(ξ)=|ξ|α(?)(ξ),對于所有α0.當(dāng)α≥1時,我們證明了柯西問題的解在Hα/2(R)上的全局適定性,當(dāng)0α1時,我們證明了柯西問題的解在Hr(R),其中rmαx{1,3/2-α}時的局部適定性,并給出了非線性部分所導(dǎo)致的解的下降形式。最后,我們用數(shù)值的方法計算并展示了當(dāng)α≥1時,解的弱色散性,以及0α1/3時解的爆破。
