HH^ZZ SheafOfRings -- cohomology of a sheaf of rings on a projective variety

Synopsis

Description

The command computes the i-th cohomology group of R as a vector space over the coefficient field of X.

i1 : Cubic = Proj(QQ[x_0..x_2]/ideal(x_0^3+x_1^3+x_2^3))

o1 = Cubic

o1 : ProjectiveVariety
i2 : HH^1(OO_Cubic)

       1
o2 = QQ

o2 : QQ-module, free
