三维本原方程在$L^p$ -空间中的整体强适定性

Global Strong Well-posedness of the Three Dimensional Primitive equations in $L^p$-spaces

Matthias Hieber, Takahito Kashiwabara

摘要:

本文发展了求解原始方程的一种$L^p$方法。特别是,它表明,三维原始方程承认一个唯一的,全球强解的所有初始数据$a \in [X_p,D(A_p)]_{1/p}$提供$p \in [6/5,\infty)$。为此,流体静力Stokes算子$A_p$定义在$X_p$上,$X_p$是与流体静力Helmholtz投影相关的$L^p$的子空间。选择大的$p$,获得原始方程的全局适定性,用于具有比$H^1$更少的可微性的初始数据$a$的强解,由此特别地推广Cao和Titi的结果(Ann.Math.166(2007),pp. 245-267)的情况下,非光滑的初始数据。

英文摘要:

In this article, an $L^p$-approach to the primitive equations is developed. In particular, it is shown that the three dimensional primitive equations admit a unique, global strong solution for all initial data $a \in [X_p,D(A_p)]_{1/p}$ provided $p \in [6/5,\infty)$. To this end, the hydrostatic Stokes operator $A_p$ defined on $X_p$, the subspace of $L^p$ associated with the hydrostatic Helmholtz projection, is introduced and investigated. Choosing $p$ large, one obtains global well-posedness of the primitive equations for strong solutions for initial data $a$ having less differentiability properties than $H^1$, hereby generalizing in particular a result by Cao and Titi (Ann. Math. 166 (2007), pp. 245-267) to the case of non-smooth initial data.
