What does the \lambda mean here?

comment Total complex homology exact sequence
I think you mean $d_{p,q}^v(b)=0$ on the third line numerator.

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 $H^0(\mathbb R^n,\mathbb R^n_0;\mathbb Z)\to H^0(\mathbb R^n;\mathbb Z)\to H^0(\mathbb R^n_0;\mathbb Z)\to H^1(\mathbb R^n,\mathbb R^n_0;\mathbb Z)\to \cdots$?

comment Regional Mathematics Olympiad(RMO-India) Geometry Problem
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.

comment Regional Mathematics Olympiad(RMO-India) Geometry Problem
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.
