   Format: MarkdownItexat _[[singular homology]]_ I have * made push-forward of singular simplices and functoriality of the singular complex $C_\bullet(-)$ manifest in the Definition-section; * stated in the Properties-section more explicitly that $C_\bullet(-)$ sends weak homotopy equivalences to quasi-isomorphisms.
