boundopen_question
Erdős Problem #1176 has status 'not disprovable'. Statement: Let $G$ be a graph with chromatic number $\aleph_1$. Is it true that there is a colouring of the edges with $\aleph_1$ many colours such that, in any countable colouring of the vertices, there exists a vertex colour containing all edge colours? A problem of Erdős, Galvin, and Hajnal. The consistency of this was proved by Hajnal and Komjáth. Topics: set theory, chromatic number. Erdős prize: no. Statement is machine-verified in Lean (formal-conjectures). OEIS: N/A.
