spectralSequence -- construct a spectral sequence

Synopsis

Usage:

E = spectralSequence K
Inputs:
- K, a filtered chain complex, A filtered complex
Optional inputs:
- Prune => ..., default value false,
Outputs:
- E, a spectral sequence,

Description

This is the primitive spectral sequence constructor.

In the example below we construct a spectral sequence $E$ from the filtered complex $K$.

i1 : B = QQ[a..d];

i2 : J = ideal vars B;

o2 : Ideal of B

i3 : C = complete res monomialCurveIdeal(B,{1,3,4});

i4 : K = filteredComplex(J,C,4);

i5 : E = spectralSequence K

o5 = E

o5 : SpectralSequence

To view pages and or maps we proceed, for example, as follows (note we suppress the output of the E^0.dd command to prevent excessive output)

i6 : E^0
