Cohomology of varieties defined solely by their embedding equation

61 Views Asked by At

In textbooks where sheaf cohomology is introduced, example computations are typically carried out on known spaces, e.g. $\mathbb{P}^n$.

However, suppose we are handed a description of a variety solely by its defining equation, e.g.,

$$v^2w + w^2x + x^2y + y^2z + z^2v = 0$$

where $x,y,z,w,v$ are homogeneous coordinates on $\mathbb{P}^4$. How does one then go about finding different sheaf cohomology groups or for example the Hodge diamond, when what the space “is” is not explicit?(The example is the Klein cubic 3-fold.)

My initial guess is to see if it’s reducible, etc, and try to find an acyclic covering, from which I could use the Cech complex.

(For example for $x^2 + y^2 + z^2=0$ in $\mathbb{A}^3_{\mathbb{R}}$, we would use $X = S^2$.)
