comment Fermat's proof for $x^3-y^2=2$
There may be more than one way of writing numbers in the form $a^2+2b^2$. So the last para doesn't seem clear to me.

comment Asymptotic expansion of a sequence given by an integral with reciprocal Gamma function
Yes, that's right -- $1/(\log n)^2$.

comment Asymptotic expansion of a sequence given by an integral with reciprocal Gamma function
It's about $n/(\log n)^2$. The integral is dominated by the region near $1$, where you can use $-1/\Gamma(x-1)=(1-x) + O((1-x)^2)$ ...
