isSubset(MultiprojectiveVariety,MultiprojectiveVariety) -- whether one variety is a subvariety of another

• Function: isSubset

• Usage:

  isSubset(X,Y)

• Inputs:
  • X, a multi-projective variety
  • Y, a multi-projective variety
• Outputs:
  • a Boolean value, whether X is contained in Y

i1 : Y = PP_(ZZ/33331)^(2,2);

o1 : ProjectiveVariety, surface in PP^5

i2 : X = point Y;

o2 : ProjectiveVariety, a point in PP^5

i3 : isSubset(X,Y)

o3 = true

i4 : isSubset(Y,X)

o4 = false
