Statement

Proposition

The category of Delta-generated topological spaces carries the structure of a cofibrantly generated model category with the same generating (acyclic) cofibrations as for the classical model structure on topological spaces and such that the coreflection into all topological spaces (this Prop.) is a Quillen equivalence with the classical model structure on topological spaces:

$Top_{Qu} \underoverset {\underset{Cdfflg}{\longrightarrow}} {\hookleftarrow} {\;\;\;\;\;\simeq_{\mathrlap{Qu}}\;\;\;\;\;} D Top_{Qu}$

By the same kind of argument (Gaucher 2007), this factors by a Quillen equivalence through the model structure on compactly generated topological spaces:

$Top_{Qu} \underoverset { \underset{ k }{\longrightarrow} } { {\hookleftarrow} } { \;\;\;\;\;\;\simeq_{\mathrlap{Qu}}\;\;\;\;\;\; } k Top_{Qu} \underoverset { \underset{ D }{\longrightarrow} } { {\hookleftarrow} } { \;\;\;\;\;\;\simeq_{\mathrlap{Qu}}\;\;\;\;\;\; } D Top_{Qu} \,.$
