Selective separability on spaces with an analytic topology
J. Camargo, C. Uzcategui
We study two form of selective selective separability, and , on countable spaces with an analytic topology. We show several Ramsey type properties which imply . For…

Some topological and combinatorial properties preserved by inverse limits
Javier Camargo, Carlos Uzcategui
We show that the following properties are preserved under inverse limits: countable fan-tightness, q+, discrete generation and selective separability. We also present several examp…
