Coherence for Invertible Objects and Multi-graded Homotopy Rings

Abstract

We prove a coherence theorem for invertible objects in a symmetric monoidal category. This is used to deduce associativity, skewcommutativity, and related results for multi-graded morphism rings, generalizing the well-known versions for stable homotopy groups.
