D.4.5.9 AssEHV
Procedure from library ehv.lib (see ehv_lib).
- Usage:
- AssEHV(I [,Strategy]); I Ideal, Strategy list
- Return:
- a list, the associated prime ideals of I
- Note:
- Uses the algorithm of Eisenbud/Huneke/Vasconcelos.
The (optional) second argument determines the strategy used:
Strategy[1] > strategy for the equidimensional part
= 0 : uses equiMaxEHV
= 1 : uses equidimMax
Strategy[2] > strategy for the equidimensional radical
= 0 : uses equiRadEHV
= 1 : uses equiRadical
Strategy[3] > strategy for equiRadEHV
= 0 : combination of strategy 1 and 2
= 1 : computation of the radical just with the
help of regular sequences
= 2 : does not try to find a regular sequence
Strategy[4] > strategy for the computation of ideal quotients
= n : uses quot(.,.,n) for the ideal quotient computations
If no second argument is given, Strategy=(0,0,0,0) is used.
