The girth Ramsey theorem

Combinatorics 2023-08-31 v1

Abstract

Given a hypergraph FF and a number of colours rr, there exists a hypergraph HH of the same girth satisfying H(F)rH\longrightarrow (F)_r. Moreover, for every linear hypergraph FF there exists a Ramsey hypergraph HH that locally looks like a forest of copies of FF.
