Abstract: We show how decreasing diagrams introduced in the theory of rewriting systems can be used to prove coherence type theorems in category theory. We apply this method to describe a coherent presentation of the 0-Hecke monoid H(Σn) of the symmetric group Σn , i.e. a presentation by generators, relations, and relations between relations.
