Cohomology of Homogeneous Complex Manifolds
In the question $G$ is a semisimple algebraic group, which does not seem to be the case for your "counterexample".

K3 surface as an anticanonical section
One comes close with the following example: Consider $V = S \times \mathbb{P}^1$. Here each anticanonical divisor is isomorphic to either two copies of $S$ or $S$ doubled.

Numbers represented by inhomogeneous forms
To those people who are voting to close: could you please explain why? Perhaps I am missing something, but this question seems nontrivial to me.

Backlund counting formula for Dirichlet Lfunctions?
I'm voting to close this question as offtopic because it's no longer relevant.

The topology of Fano schemes of lines
@Jason: You must be missing some cases. For example, the Fano scheme of lines on a smooth cubic threefold is a smooth surface with nontrivial fundamental group, however this does not appear in the list which you give.

Why are solutions to $\sqrt[k]{x_1^k+x_2^k+x_3^k+x_4^k}$ for $k=2,3$ curiously smooth?

A question about Weil restriction
@AllyMath: I don't really have an answer, only an idea how one would calculate it. Why do you want an explicit description so much anyway? Often in applications one only needs to know the cohomology, which one can easily calculate using the Leray spectral sequence.

A question about Weil restriction
Calculating the Weil restriction of a constant group scheme should be similar to calculating the pushforward of the structure sheaf $\pi_* \mathcal{O}_C$. You should get some complicated answer in terms of things like the ramification data of the cover. A simpler thing to understand is the generic fibre of this, which is just the Weil restriction of a constant group scheme with respect to a quadratic field extension.

Stabilisers of group actions
This seems pretty cool, however it is so technical I'm struggling to understand it. Is it possible to give an intuitive idea of where it comes from? Is this a standard example or your own example? Is it perhaps related to some kind of moduli problem or something in GIT?

Stabilisers of group actions
This is great, thanks! Out of interest, do you happen to know an example for which the answer to my question is no? e.g. for some nonreductive group $G$ which acts with nonclosed orbits?.

Dirichlet series without order term
Could you please clarify what you mean by "Dirichlet series without the order term"? Do you mean series of the shape $\sum_{n=\infty}^\infty a_n/n^s$?
