pdim(CoherentSheaf) -- calculate the projective dimension

Synopsis

Description

i1 : V = Proj(ZZ/101[x_0..x_2]);
i2 : S = sheaf(image matrix {{x_0^3+x_1^3+x_2^3}})

o2 = image | x_0^3+x_1^3+x_2^3 |

                                         1
o2 : coherent sheaf on V, subsheaf of OO
                                        V
i3 : pdim S

o3 = 0
