On the geometric realization and subdivisions of dihedral sets

Sho Saito

Algebraic & Geometric Topology 13 (2013) 1071–1087
Abstract

We extend to dihedral sets Drinfeld’s filtered-colimit expressions of the geometric realization of simplicial and cyclic sets. We prove that the group of homeomorphisms of the circle continuously act on the geometric realization of a dihedral set. We also see how these expressions of geometric realization clarify subdivision operations on simplicial, cyclic and dihedral sets defined by Bökstedt, Hsiang and Madsen, and Spaliński.

Keywords
