Kolmogorov widths of an intersection of anisotropic finite-dimensional balls: case $2 \leq q_{j} < \infty$

A. A. Vasil'eva

Order estimates for the Kolmogorov $n$ -widths of $\cap_{α \in A} ν_{α} B_{p}^{k}$ in $l_{q}^{k}$ are obtained; here $\overline{q}=(q_1, \,…

A. A. Vasil'eva

In this paper, order estimates for the Kolmogorov $n$ -widths of an intersection of an arbitrary family of balls $ν_{α} B_{p_{α}}^{k}$ in $l_{q}^{k}$ are obtained for $…
