On $2$ -stationarity of $P_{I^} º I^»$

Hiroshi Sakai, M. Catalina Torres

The notion of $n$ -stationary subsets of $P_{I^} º I^»$ for $n < I ¨ $ were introduced and studied by Cody, Lambie-Hanson \& Zhang \cite{CLHZ} and Torres \cite{T}. They proved tha…

Higher stationarity and derived topologies on $P_{I^} º (A)$

M. Catalina Torres

Let $I^º$ be a regular limit cardinal, $I^º \subseteq A$ . We study a notion of $n$ -s-stationarity on $P_{I^} º (A)$ . We construct a sequence of topologies $\langle Ï_0, Ï_1, \d…
