| Jan 29, 2017 at 22:15 | comment | added | Jason Starr | Consider any short exact sequence as a complex $C$ concentrated in three consecutive degrees. If this complex is null homotopic, the same is true after applying any additive functor $F$. Yet typically the homology of $F(C)$ is nonzero (and this is the main motivation behind the development of homological algebra). | |
