initialDegree -- compute the initial degree of a graded ideal

Synopsis

• Usage:

  initialDegree I

• Inputs:
  • I, a graded ideal
• Outputs:
  • an integer, representing the initial degree of the ideal I

Description

Example:

i1 : E=QQ[e_1..e_4,SkewCommutative=>true]

o1 = E

o1 : PolynomialRing, 4 skew commutative variables

i2 : initialDegree ideal {e_1*e_2,e_2*e_3*e_4}

o2 = 2

i3 : initialDegree ideal {e_1*e_3*e_4}

o3 = 3
