本文讨论了有限维子空间上函数的积分范数的离散化问题。本文提出了一种新的积分范数离散化方法,该方法能很好地解决积分范数的离散化问题。它是基于链接的概率技术和统一范数中熵数的结果的组合。
This paper is devoted to discretization of integral norms of functions from a given finite dimensional subspace. This problem is very important in applications, but there is no systematic study of it. We present here a new technique, which works well for discretization of the integral norm. It is a combination of probabilistic technique, based on chaining, and results on the entropy numbers in the uniform norm.
