Thank you. I did not expect it to be that messy!

Homotopy type of a locally contractible compact
@BS: I had in mind "standard" one, but I can afford stronger versions too, if it makes a difference.

Is the Duflo polynomial conjecture open?
They are subalgebras of polynomial algebras. In cases I remember they are polynomial, but I doubt it is always so. The interesting problem here is not exactly to prove that they are isomorphic, but to find a natural isomorphism. Also, both algebras have natural filtrations, and I think a decent isomorphism is supposed to preserve it.

I mean, I know this reference, but this does not help me to answer the question.

Isn't it a bit old?

But symmetric spaces are well known to be commutative in this sense. So, I do not see where this helps.

Degrees of maps from curves to $\mathbb P^1$
For an elliptic curve, there are maps of degree 2 and 3, but no map of degree 1. In this case, the bound is sharp.

You are probably right. But I am not sure I understand why the strict transform is isomorphic to $S$, not only birationally equivalent.

A short proof for $\dim(R[T])=\dim(R)+1$
@Martin Brandenburg: Well, I was wrong again. Sorry about bothering you. Anyway, I think you asked a good question. I upvoted it.
