getPrimeDivisors -- get the list of prime divisors of a given divisor

• Usage:

  getPrimeDivisors( D1 )

• Inputs:
  • D1, an instance of the type BasicDivisor,
• Outputs:
  • a list,

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

i2 : D = divisor({-8, 2, 0}, {ideal(x), ideal(y), ideal(x^2+z)})

o2 = 2*Div(y) + 0*Div(x^2+z) + -8*Div(x)

o2 : WeilDivisor on R

i3 : getPrimeDivisors( D )

o3 = {Div(y), Div(x^2+z), Div(x)}

o3 : List

i4 : getPrimeDivisors( cleanSupport D )

o4 = {Div(y), Div(x)}

o4 : List
