Hom(AbstractSheaf,AbstractSheaf) -- Hom between abstract sheaves

• Function: Hom

• Usage:

  Hom(E,F)

• Inputs:
  • E, an abstract sheaf,
  • F, an abstract sheaf,
• Optional inputs:
  • DegreeLimit => ..., default value null,
  • MinimalGenerators => ..., default value true,
  • Strategy => ..., default value null,
• Outputs:
  • an abstract sheaf, the tensor product of $F$ with the dual of $E$

i1 : X = abstractProjectiveSpace 1

o1 = X

o1 : a flag bundle with subquotient ranks {2:1}

i2 : Hom(OO_X(3),OO_X)

o2 = a sheaf

o2 : an abstract sheaf of rank 1 on X

i3 : chi oo

o3 = -2
