The generalized Bolzano-Weierstrass property revisited
Ramiro de la Vega
We investigate the question of when a topological space has the : every sequence of subsets of has a convergent subsequen…
On the reflection of the countable chain condition
Ramiro de la Vega
We study the question of when an uncountable ccc topological space contains a ccc subspace of size . We show that it does if is compact Hausdorff and more general…
Countable Tightness, Elementary Submodels and Homogeneity
Ramiro de la Vega
We show (in ZFC) that the cardinality of a compact homogeneous space of countable tightness is no more than the size of the continuum.
Homogeneity properties in large compact S-spaces
Ramiro de la Vega
Under Jensen's Diamond Principle, we show how to construct a large compact S-space while having some control over its group of autohomeomorphisms. In particular we can make the spa…
A Compact Homogeneous S-space
Ramiro de la Vega, Kenneth Kunen
Under the continuum hypothesis, there is a compact homogeneous strong S-space.
