Exponential tractability of $L_{2}$ -approximation with function values

David Krieg, Pawel Siedlecki, Mario Ullrich +1

We study the complexity of high-dimensional approximation in the $L_{2}$ -norm when different classes of information are available; we compare the power of function evaluations with t…

A sharp upper bound for sampling numbers in $L_{2}$

Matthieu Dolbeault, David Krieg, Mario Ullrich

For a class $F$ of complex-valued functions on a set $D$ , we denote by $g_{n} (F)$ its sampling numbers, i.e., the minimal worst-case error on $F$ , measured in $L_{2}$ , that can be achi…
