On Weihrauch degrees of <i>k</i>-partitions of the Baire space

KGRC Research Seminar | 12.11.2015 15:00 - 16:30

In the 1990s Peter Hertling found useful "combinatorial" characterizations of initial segments of the degree structures under Weihrauch reducibilities on k-partitions (for any integer k>1) of the Baire space whose components are finite boolean combinations of open sets. In this talk we discuss extensions of these characterizations to as large initial segments of the Weihrauch degree structures as possible.
