Hajnal--Máté graphs, Cohen reals, and disjoint type guessing
Chris Lambie-Hanson, Dávid Uhrik
A Hajnal--Máté graph is an uncountably chromatic graph on satisfying a certain natural sparseness condition. We investigate Hajnal-Máté graphs and generalizations thereof, fo…
Whitehead's problem and condensed mathematics
Jeffrey Bergfalk, Chris Lambie-Hanson, Jan Šaroch
One of the better-known independence results in general mathematics is Shelah's solution to Whitehead's problem of whether implies that an abelian…
Narrow systems revisited
Chris Lambie-Hanson
Motivated by two open questions about two-cardinal tree properties, we introduce and study generalized narrow system properties. The first of these questions asks whether the stron…
