The Borel partition spectrum at successors of singular cardinals

Will Brian

Assuming that does not exist, we prove that if there is a partition of into Borel sets, then there is also a partition of into $\alep…

Combinatorial and number-theoretic properties of generic reals

Will Brian, Mohammad Golshani

We discuss some properties of Cohen and random reals. We show that they belong to any definable partition regular family, and hence they satisfy most "largeness" properties studied…

Covering versus partitioning with Polish spaces

Will Brian

Given a completely metrizable space , let denote the smallest possible size of a partition of into Polish spaces, and the smallest po…

The independence of GCH and a combinatorial principle related to Banach-Mazur games

Will Brian, Alan Dow, Saharon Shelah

It was proved recently that Telgársky's conjecture, which concerns partial information strategies in the Banach-Mazur game, fails in models of . The proof int…

Telgarsky's conjecture may fail

Will Brian, Alan Dow, David Milovich +1

Telgársky's conjecture states that for each , there is a topological space such that in the Banach-Mazur game on , the player {\scriptsize NONEMPTY} has…

Small cardinals and small Efimov spaces

Will Brian, Alan Dow

We introduce and analyze a new cardinal characteristic of the continuum, the \emph{splitting number of the reals}, denoted . This number is connected to Ef…
