关于流形上索伯列夫空间的compactness的亏损

On defect of compactness for Sobolev spaces on manifolds

Leszek Skrzypczak, Cyril Tintarev

摘要:

关于两个巴拿赫空间E和F的嵌入的紧性缺陷是E中的弱收敛序列与其在F的范数中为零的余数上的弱极限之间的差。特别是对于Sobolev嵌入,紧性的缺陷被表示为剖面分解-一个项的总和,称为基本浓度,具有渐近不相交的支持。讨论了一类具有有界几何的黎曼流形的索伯列夫空间的剖面分解,该剖面分解是与定义在不同于M的流形上的浓度剖面相关联的基本浓度的和,这些浓度剖面是由一个极限过程诱导的.的配置文件满足Plancherel型的不等式,和一个类似的关系,有关Brezis-Lieb引理,持有相应的流形上的配置文件的Lebesgue规范。

英文摘要:

Defect of compactness, relative to an embedding of two Banach spaces E and F, is a difference between a weakly convergent sequence in E and its weak limit taken up to a remainder that vanishes in the norm of F. For Sobolev embeddings in particular, defect of compactness is expressed as a profile decomposition - a sum of terms, called elementary concentrations, with asymptotically disjoint supports. We discuss a profile decomposition for the Sobolev space of a Riemannian manifold with bounded geometry, which is a sum of elementary concentrations associated with concentration profiles defined on manifolds different from M, that are induced by a limiting procedure. The profiles satisfy an inequality of Plancherel type, and a similar relation, related to the Brezis-Lieb Lemma, holds for Lebesgue norms of profiles on the respective manifolds.
