Mar 1, 2013 at 5:19 | comment | added | Marc Hoyois | Hey Dylan! The square for the Mayer-Vietoris sequence is in fact a homotopy pushout even before stabilizing. That's not a completely trivial fact, however, as it immediately implies the standard Seifert-van Kampen theorem. For an elementary proof see Theorem A.3.1 in Higher Algebra. | |
