Cyclic sets from the nerve of a group and the Böhm-Ştefan construction

John Boiquaye

Böhm and Ştefan developed a general method of construction of cyclic objects from (op)algebras over distributive laws of monads. The goal of this note is to show that all the cyclic sets resulting from the twisted nerve of a group G arise from the Böhm-Ştefan construction.

Keywords: cyclic objects, duplicial objects, twisted nerved of a group, Böhm-Ştefan construction
