The assertion is that X0 ⊔fX1 and X0 ⊔gX1 are subspaces of X0 ⊔F(X1×I), so in particular the quotient topologies on X0 ⊔fX1 and X0 ⊔gX1 are the same as the subspace topologies from X0 ⊔F(X1×I ... raya and the last dragon plus

"WebDec 19, 2015 · I am doing a self-study in algebraic topology and have a question about Hatcher's Ex.0.6(b) and contractibility on p18. There have been several other posts concerning why the "zigzag comb" (space Y) is not deformation retractable, and that part is very clear to me. But my question concerns why it IS contractible.
