Decomposition spaces, incidence algebras and Möbius inversion III: the decomposition space of Möbius intervals

Decomposition spaces are simplicial 8-groupoids subject to a certain exactness condition, needed to induce a coalgebra structure on the space of arrows. Conservative ULF functors between decomposition spaces induce coalgebra homomorphisms. Suitable added finiteness conditions define the notion of Mö...
