minimalPart -- intersection of the minimal components

• Usage:

  minimalPart(I)

• Inputs:
  • I, an ideal,
• Outputs:
  • an ideal, the intersection of the components of I corresponding to minimal primes

i1 : R = QQ[x,y,z]

o1 = R

o1 : PolynomialRing

i2 : J = intersect(ideal(x^2,y,z^3),ideal(x,z))

                       2   3
o2 = ideal (y*z, x*y, x , z )

o2 : Ideal of R

i3 : minimalPart(J)

o3 = ideal (z, x)

o3 : Ideal of R
