A Sacks indestructible co-analytic maximal eventually different family

Vera Fischer, David Schrittesser

In the constructible universe, we construct a co-analytic maximal family of pairwise eventually different functions from $N$ to $N$ which remains maximal after ad…

Lebesgue's Density Theorem and definable selectors for ideals

Sandra Müller, Philipp Schlicht, David Schrittesser +1

We introduce a notion of density point and prove results analogous to Lebesgue's density theorem for various well-known ideals on Cantor space and Baire space. In fact, we isolate…

Maximal almost disjoint families, determinacy, and forcing

Karen Bakke Haga, David Schrittesser, Asger Törnquist

We study the notion of $J$ -MAD families where $J$ is a Borel ideal on $ω$ . We show that if $J$ is an arbitrary $F_{σ}$ ideal, or is any finite or countably…
