Cardinal Characteristics on Bounded Generalised Baire Spaces

Logic 2025-03-17 v2

Abstract

We will give an overview of four families of cardinal characteristics defined on subspaces ακb(α)\prod_{\alpha\in\kappa}b(\alpha) of the generalised Baire space κκ{}^\kappa\kappa, where κ\kappa is strongly inaccessible and bκκb\in{}^\kappa\kappa. The considered families are bounded versions of the dominating, eventual difference, localisation and anti-localisation numbers, and their dual cardinals. We investigate parameters for which these cardinals are non-trivial and how the cardinals relate to each other and to other cardinals of the generalised Cicho\'n diagram. Finally we prove that different choices of parameters may lead to consistently distinct cardinals.
