IdealLcm

Least common multiplier of 2 ideals.

Syntax:

I:=IdealLcm(I1, I2);

Ideals
  I, I1, I2  

Description:

The lcm of \a and \b is computed as frac{\a\b}{\a+\b}. The order over which the ideals are defined must be maximal.


Example:


kash> O:=OrderMaximal(Order(Poly(Zx,[1,6,6,6])));
Generating polynomial: x^3 + 6*x^2 + 6*x + 6
Discriminant: -1836 

kash> I1:=Ideal(18,Elt(O,[0,0,1]));
<18, [0, 0, 1]>
kash> I2:=Ideal(24,Elt(O,[0,0,1]));
<24, [0, 0, 1]>
kash> IdealLcm(I1,I2);
> <
[6 0 0]
[0 6 0]
[0 0 1]
