On totally Lindelöf spaces

Gabriel Fernandes, Guilherme Pinto, Vinícius Rocha

The results in this paper answer three questions asked by (NOBLE, 2019) and give a partial answer to a question asked by (ALSTER, 1988). We prove that every Alster space is totally…

Partitions of topological spaces and a new club-like principle

Rodrigo Carvalho, Gabriel Fernandes, Lúcia R. Junqueira

We give a new proof of the following theorem due to W. Weiss and P. Komjath: if is a regular topological space, with character and $X \rightarrow (top ω+ 1)^{…

On Local Club Condensation

Gabriel Fernandes

We obtain results on the condensation principle called local club condensation. We prove that in extender models an equivalence between the failure of local club condensation and s…

Fake reflection

Gabriel Fernandes, Miguel Moreno, Assaf Rinot

We introduce a generalization of stationary set reflection which we call "filter reflection", and show it is compatible with the axiom of constructibility as well as with strong fo…

Inclusion modulo nonstationary

Gabriel Fernandes, Miguel Moreno, Assaf Rinot

A classical theorem of Hechler asserts that the structure is universal in the sense that for any -directed poset P with no maximal element, there is a c…

Tall cardinals in extender models

Gabriel Fernandes, Ralf Schindler

Assuming that there is no inner model with a Woodin cardinal, we obtain a characterization of -tall cardinals in extender models that are iterable. In particular we prove that i…
