In mathematics, the Koszul complex was first introduced to define a cohomology theory for Lie algebras, by Jean-Louis Koszul (see Lie algebra cohomology). It turned out to be a useful general construction in homological algebra. As a tool, its homology can be used to tell when a set of elements of a (local) … See more Let R be a commutative ring and E a free module of finite rank r over R. We write $${\displaystyle \bigwedge ^{i}E}$$ for the i-th exterior power of E.

USING A MODIFIED KOSZUL COMPLEX The above argument is fairly straightforward, but we can also use commutativity to explicitly construct lifts of elements of the kernel in a modified Koszul complex. This method is somewhat more complicated, because we can have to show that our lift is actually a lift (which involves using hIiin detail). http://webdoc.sub.gwdg.de/ebook/serien/e/mpi_mathematik/2008/52.pdf marilyn manson coma white tekst
