ddSequences and Partial EulerPoincare' Characteristics of Koszul
Complex Nguyen Tu Cuong and Doan Trung Cuong
Abstract. The aim of this short note
is to give new concept of sequences called ddsequences, which is a slight
generalization of the notion of unconditioned strong dsequence. Then we
apply these ddsequences to stady the polynomial property of the lengths
of Koszul homology and of local cohomology modules with respect to the powers
of a system of parameters. A completion of all proofs of statements given
here the readers can find in [3].
