Abstract

The current work studies the limitwise monotonic spectra introduced by Downey, Kach and Turetsky [6]. In the first part of the paper, we study the limitwise monotonic spectra of subsets and sequences of subsets of \(\mathbb N\). In particular, we study their measure-theoretical and topological properties. Then we generalize them to the spectra of subsets and sequences of subsets of \(\mathbb R\) and provide some new degree spectra of structures.

The work is supported by the Russian Science Foundation (grant no. 18-11-00028) and performed under the development program of Volga Region Mathematical Center (agreement no. 075-02-2020-1478).
