multidegree(MultiprojectiveVariety) -- the multidegree of the variety

Synopsis

• Function: multidegree

• Usage:

  multidegree X

• Inputs:
  • X, a projective variety
• Outputs:
  • the multi-degree of the defining ideal of $X$

Description

i1 : X = projectiveVariety ideal random({2,1},ZZ/101[x_0,x_1,x_2,y_0,y_1,Degrees=>{3:{1,0},2:{0,1}}]);

o1 : ProjectiveVariety, surface in PP^2 x PP^1

i2 : multidegree X

o2 = 2T  + T
       0    1

o2 : ZZ[T ..T ]
         0   1
