Talk:Mapping cone (topology)

K-Theory
Something about the mapping cone of a map of c*-algebras is missing. cf. N.E. Wegge-Olsen: K-Theory and C*-Algebras.

Beyond ridiculous
This is the first sentence of the article:

""In mathematics, especially homotopy theory, the mapping cone is a construction of topology, analogous to a quotient space."

It is beyond ridiculous to call the mapping cone "analogous to" a quotient space, because '''a mapping cone is a quotient space.
