Weakened Gallai-Ramsey Numbers for Books

Mark Budden, Adam Gregory

For $1 \leq s < t$ and any graph $G$ , the weakened Gallai-Ramsey number $g r_{s}^{t} (G)$ is defined to be the least $p \in N$ such that every Gallai $t$ -coloring of the edges of $K_…

The chain replacement of a poset flow

Philippe Gaucher

The paper defines the chain replacement of a poset flow, converting finite posets into q‑cofibrant flows using simplicial nerves, and proves that pushouts along these replacements…
