hilbertNumerator -- calculate Hilbert numerator from Hilbert function

Synopsis

• Usage:

  p=hilbertNumerator(L,r,t)

• Inputs:
  • L, a list, values of the hilbert function
  • r, an integer, dimension of ambient projective space
  • t, a ring element, variable in which the hilbertNumerator is given

Description

i1 : T=QQ[t];

i2 : hilbertNumerator({0,0,4,6,3,0,0,0,0},3,t)
