Meagre and Null Ideals for Uncountable Cardinals

20.03.2025 15:00 - 15:50

T. van der Vlugt (TU Wien)

We will consider the space of functions from \(\lambda\) to \(\kappa\) for various choices of \(\lambda\) and \(\kappa\). In the first part of the talk we define topologies on such spaces and discuss the \(\mu\)-meagre ideal (i.e. sets that are unions of \(\mu\)-many nowhere dense sets) and their associated cardinal invariants. In the second part, we will look at various ways to look at (cardinal invariants of) the null ideal on such spaces.
