Every subset of a topological Ramsey space is Ramsey in the Solovay model

Clement Yung

We provide a proof, free of ultrafilters and almost reduction, that every subset of a topological Ramsey space is Ramsey in the Solovay model.

Full mad families of vector spaces and two local Ramsey theories

Clement Yung

Let $E$ be a vector space over a countable field of dimension $ℵ_{0}$ . Two infinite-dimensional subspaces $V, W \subseteq E$ are almost disjoint if $V \cap W$ is finite-dimension…

Weak A2 spaces, the Kastanas game and strategically Ramsey sets

Clement Yung

We introduce the notion of a weak A2 space (or wA2-space), which generalises spaces satisfying Todorčević's axioms A1-A4 and countable vector spaces. We show that in any Polish wea…
