stableIdeal -- compute the smallest stable ideal in an exterior algebra containing a given monomial ideal

Synopsis

• Usage:

  stableIdeal I

• Inputs:
  • I, a monomial ideal of an exterior algebra
• Outputs:
  • an ideal, the smallest stable ideal containing ideal I

Description

Example:

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

o1 = E

o1 : PolynomialRing, 4 skew commutative variables

i2 : stableIdeal ideal {e_2*e_3}

o2 = ideal (e e , e e )
             1 2   2 3

o2 : Ideal of E
