Higher-dimensional Delta-systems
Chris Lambie-Hanson
We investigate higher-dimensional -systems indexed by finite sets of ordinals, isolating a particular definition thereof and proving a higher-dimensional version of the classica…
A note on highly connected and well-connected Ramsey theory
Chris Lambie-Hanson
We study a pair of weakenings of the classical partition relation recently introduced by Bergfalk-Hrušák-Shelah and Bergfalk, respectively. Given an edge-col…
Disjoint type graphs with no short odd cycles
Chris Lambie-Hanson
In this note, we provide a proof of a technical result of Erdős and Hajnal about the existence of disjoint type graphs with no odd cycles. We also prove that this result is sharp i…
Extremal triangle-free and odd-cycle-free colourings of uncountable graphs
Chris Lambie-Hanson, Dániel T. Soukup
The optimality of the Erdős-Rado theorem for pairs is witnessed by the colouring recording the least point of disagreement between two functions. This…
Separating diagonal stationary reflection principles
Gunter Fuchs, Chris Lambie-Hanson
We introduce three families of diagonal reflection principles for matrices of stationary sets of ordinals. We analyze both their relationships among themselves and their relationsh…
