On greedy approximation in complex Banach spaces
A. Gasnikov, V. Temlyakov
The general theory of greedy approximation with respect to arbitrary dictionaries is well developed in the case of real Banach spaces. Recently, some of results proved for the Weak…

Sampling discretization error of integral norms for function classes with small smoothness
V. N. Temlyakov
We consider infinitely dimensional classes of functions and instead of the relative error setting, which was used in previous papers on the integral norm discretization, we conside…
