D.6.11.5 H2basis

Procedure from library mondromy.lib (see mondromy_lib).

Usage:
H2basis(f); f poly

Assume:
The polynomial f in a series ring (local ordering) defines an isolated hypersurface singularity.

Return:
The procedure returns a list of representatives of a C{f}-basis of the Brieskorn lattice H"=Omega^(n+1)/df^dOmega^(n-1).

Theory:
H" is a free C{f}-module of rank milnor(f).

Display:
The procedure displays more comments for higher printlevel.

Example:
