A hierarchy of filters on regular uncountable cardinals
Published online by Cambridge University Press: 12 March 2014
Abstract
We introduce a well-founded relation < between filters on the space of descending sequences of ordinals. For each regular uncountable cardinal κ, the length of the relation is an ordinal o(κ) ≤ (2κ)+.
