dc.description.abstract | We prove several theorems about the cardinal associated with groupwise density. With respect to a natural ordering of families of nond-ecreasing maps from ω to ω , all families of size are below all unbounded families. With respect to a natural ordering of filters on ω , all filters generated by sets are below all non-feeble filters. If then and . (The definitions of these cardinals are recalled in the introduction.) Finally, some consequences deduced from by Laflamme are shown to be equivalent to . | en_US |
