WebOct 16, 2013 · Abstract. The most fundamental complexes of free modules over a commutative ring are the Koszul complex, which is constructed from a vector (i.e., a 1 1 1-tensor), and the Eagon--Northcott and Buchsbaum--Rim complexes, which are constructed from a matrix (i.e., a 2 2 2-tensor).The subject of this paper is a multilinear analogue of … Web34.
