D.15.2.7 globalSections
Procedure from library divisors.lib (see divisors_lib).
- Usage:
- globalSections(A); A = divisor.
- Assume:
- A is a divisor on X.
- Return:
- a list with a basis of the space of global sections of D.
- Theory:
- We assume that the qring of X satisfies the S2-condition. We compute sat((f*J) : I) /f
where D = (I)-(J).
