Cardinal invariants of analytic P-ideals
National University of Singapore
I will introduce several cardinal invariants associated with analytic P-ideals, concentrating on the ideal of sets of asymptotic density zero. I will give a summary of some recent work on these invariants relating them to the dominating, bounding and splitting numbers, and to some variants of the splitting number. Several fundamental problems remain open and I will try to discuss as many of these as I can.
