comment Simplifying a generating function in two variables with two binomial coefficients
@Did not really, I mean that's the position that I started from, since the Chern class of a direct sum is the product of the Chern classes of the summands. I abandoned this question since I didn't get any other answers, but I guess yours is as close as I can get.

comment Relative cohomology of a vector space module non-zero vectors
Of course. Thanks! If you want to make that an answer I'll be sure to accept it.

comment Relative cohomology of a vector space module non-zero vectors
Yes, that is actually quite useful. So everything can be computed just using the sequence $H^0(\mathbb R^n,\mathbb R^n_0;\mathbb Z)\to H^0(\mathbb R^n;\mathbb Z)\to H^0(\mathbb R^n_0;\mathbb Z)\to H^1(\mathbb R^n,\mathbb R^n_0;\mathbb Z)\to \cdots$?

Watch your assertions there, guy. I have zilch idea of what level your competition is at; there are competitions where this type of language is used to mask a simple problem, i.e. one where any specific situation simplifies to the general case.

My bad, I'm not familiar with the RMO-India question setup. Questions posed in this way in competitions I've gone to can be solved in this way.

comment What is the metric tensor on the n-sphere (hypersphere)?
Great, thanks for the step-by-step explanation. Although what you've written is fairly clear, you can make it clearer by using the TeX environment, with the $ delimiters, like instead of g'rϕk, write $g'_{r\phi_k}$, which comes out as $g'_{r\phi_k}$.
