Factorial of 3/2?
@quid: I wondered why people were suddenly downvoting and closing a question that had been dormant for over 5 years. The answer was my earlier comment.

Real and imaginary part of an holomorphic function
Notice he assumes $f$ is (complex) differentiable, but not that $f$ is $C^1$.

When does $\overline{U(0,1)}=B(0,1)$ hold?
and "value group dense" does not change the fact that all open balls are closed sets.

An upper bound for the length of the continued fraction expansion of $\sqrt d$
That $\Omega$ is not consistent with the cases of $\ell=0$ in the question. I think it actually says $\ell(d)$ is not $o(\sqrt{d}/\log\log d)$.

Does the Brouwer fixed point theorem admit a constructive proof?
So: Would L.E.J. Brouwer himself accept the proof?

Notation for $\log \log \cdots \log n$?
To carefully specify composition, we can use $\log^{\circ k} n$

Is the space of all borel measures on $\mathbb R^n$ isomorphic to the tensor product of spaces of borel measures on $\mathbb R$?
Isomorphic in what sense? They are vector spaces of the same Hamel dimension...

He used $\mathcal L$ for what you would call Lebesgue outer measure.

No simple expression like this has halfexponential growth. See my answer here mathoverflow.net/a/45479/454

Is a sigmafinite Borel measure over $\mathbb R$ determined by its values on the continuous functions?
Looks $\sigma$finite to me.

What was the answer to this paradox before Cantor?
