Cardinal characteristics modulo nice ideals on omega

Many of the standard cardinal characteristics of the continuum in terms of a relation holding almost everywhere, where "almost everywhere" means on all but a finite set. A very natural generalisation is to take "almost everywhere" to mean on all but a member of a given ideal. I will talk about what happens when we do this, with the density 0 ideal on \(\omega\) as a focal example.

Students at Uni Wien are required to attend in person.
