Abstract:
Based on the well-known cardinal characteristics , and , we introduce nine related cardinal characteristics by using the notion of asymptotic density to characterise different intersection properties of infinite sets. We prove several bounds and consistency results, e.g. the consistency of , as well as several results about possible values of i1/2.
