Joins for (Augmented) Simplicial Sets

Category Theory 2007-05-23 v1 Algebraic Topology

Abstract

We introduce a notion of join for (augmented) simplicial sets generalising the classical join of geometric simplicial complexes. The definition comes naturally from the ordinal sum on the base simplicial category Δ\Delta.
