## Spectral sequence [closed]

what is Koszul resolution? what is its role played in the computation of spectral sequence?

More globally the Koszul complex gives you a locally free resolution of $\mathcal{O}Z$ where $Z \subset X$ is the zero-set of a section of a vector bundle. This is explained, e.g. in the Appendix of Fultons Book on Interseciton theory. – Heinrich Hartmann May 26 2010 at 16:09
