D.5.6.1 intersectionDiv
Procedure from library reszeta.lib (see reszeta_lib).
- Usage:
- intersectionDiv(L);
L = list of rings
- Assume:
- L is output of resolution of singularities
(only case of isolated surface singularities)
- Compute:
- intersection matrix and genera of the exceptional divisors
(considered as curves on the strict transform)
- Return:
- list l, where
l[1]: intersection matrix of exceptional divisors
l[2]: intvec, genera of exceptional divisors
l[3]: divisorList, encoding the identification of the divisors
