Combinatorial aspects of F(sigma) filters with an application to N-sets
Claude Laflamme
We discuss F(sigma) filters and show that the minimum size of a filter base generating an undiagonalizable filter included in some F(sigma) filter is the better known bounded evasi…

Filter games and combinatorial properties of winning strategies
Claude Laflamme
We characterize winning strategies in various infinite games involving filters on the natural numbers in terms of combinatorics or structural properties of the given filter. These…

A few special ordinal ultrafilters
Claude Laflamme
We prove various results on the notion of ordinal ultrafiters introduced by J. Baumgartner. In particular, we show that this notion of ultrafilter complexity is independent of the…
