The function HIntersectionList applies the function HIntersection

to the elements of a list, i.e., HIntersectionList([I_1,...,I_n]) is

the same as HIntersection(I_1,...,I_n).

The coefficient ring must be a field.

Example

  L := [Ideal(x-z,y-2z),Ideal(x-2z,y-z)];
  HIntersectionList(L);
Ideal(x + y - 3z, y^2 - 3yz + 2z^2)
