#### Cardinal invariants of the density zero ideal

###### Dilip Raghavan (National University of Singapore)

Abstract: I will talk about some recent (and some not so recent) results on the cardinal invariants associated with the ideal of asymptotic density zero sets. In particular, I will discuss the so called weak covering and weak uniformity numbers of this ideal.
