SpectralSequences :: FilteredComplex _ ZZ

FilteredComplex _ ZZ -- the filtered pieces

Synopsis

Description

Returns the chain complex in (homological) filtration degree j. The relationship $K _ j = K ^{(-j)}$ holds. Example A = QQ[x,y]; C = koszul vars A; K = filteredComplex C K_0 K_1 K_2 K^(-1) K^(-2) K_infinity K_(-infinity) K^(- infinity) K^infinity
