The naive combinatorial model-structure conjecture
The naive combinatorial model-structure conjecture
Let be the five-point space with two open and three closed points, let be the three-point space with one open and two closed points, and let and denote the corresponding orthogonality classes. For a finite-space map , write for its non-Hausdorff mapping-cone object. Naive combinatorial model-structure conjecture. A closed model structure on the category of topological spaces is defined by taking as the cofibrations, as the trivial fibrations,
as the trivial cofibrations,
as the fibrations, and the compositions of a trivial cofibration with a trivial fibration as the weak equivalences. The conjecture proposes a purely combinatorial model structure on topological spaces, but the supplied text gives no proof or resolution.
