Program: Viera Sottova — Modification of N via ideals on omega
We consider a combinatorial characterization of the null ideal N which
we modify using ideals on omega. Resulting ideal N_J is also a sigma
ideal and additionally it is subideal of N. We focus on common cardinal
invariants of this ideal and their relation to the original ones.
Joint work with D. A. Mejia.
