Abstract:

This is a joint work with A. Prymak, A. Shadrin, V. N. Temlyakov, and S. Tikhonov. In this talk I will discuss the behavior of the entropy numbers of classes of functions with bounded integral norms from a given finite dimensional linear subspace.  Upper bounds of these entropy numbers in the uniform norm are obtained and applied to establish a Marcinkiewicz-type discretization result for these classes.
