Steklov Mathematical Institute of Russian Academy of Sciences, Moscow, Russia

Abstract: In this paper, we obtain order estimates for the Kolmogorov, Gelfand and linear widths of some discrete function classes on trees, which are generated by a two-weighted summation operator.

Keywords: поперечники, весовые операторы суммирования на дереве, весовые функциональные классы; $n$-widths, weighted summation operators, trees.
