紧致齐次黎曼流形上Sobolev类的熵

Entropy of Sobolev's classes on Compact Homogeneous Riemannian Manifolds

A. Kushpel, J. Levesley

摘要:

给出了计算任意紧致齐次黎曼流形上标准Sobolev类熵数的一般方法。我们的方法基本上是基于一个详细的研究的几何特征的规范引起的子空间的谐波。该方法的可能性并不局限于声明证明,但可以应用于研究更一般的问题,如乘子算子的熵。作为应用,我们建立了Sobolev类的熵的锐序和相应的n-宽度。

英文摘要:

We develop a general method to calculate entropy numbers of standard Sobolev's classes on an arbitrary compact homogeneous Riemannian manifold. Our method is essentially based on a detailed study of geometric characteristics of norms induced by subspaces of harmonics. The method's possibilities are not confined to the statements proved but can be applied in studying more general problems such as entropy of multiplier operators. As an application, we establish sharp orders of entropy of Sobolev's classes and respective n-widths.
