comment Diameter-area ratio for affine tranformations.
yes sure. Triangle with sides equal $d$. Its diameter is $d$, its area is $\sqrt{3}d^2/4$. But any figure spanned on two intervals of length $d$ and angle $\pi/3$ between them works as well.

comment Asymptotics vs Puiseux series
That is true, but in a question I have a finite set of pairwise comparable asymptotics, so, I evoke for properties of "good" asymptotics

comment Notion of transversality over the field of Puiseux series.
I think if they are not transversal at a point $a(t)$ then for any $t_0$ they are not transversal at the point $a(t_0)$

comment Area of a lattice polygon in terms of its width
@Ilya: I had started this bounty before I realized that it is a simple problem, and I was very nervous =)) Now I can not cancel it. Concerning the first comment: an affine transformation preserves the lattice width, it is enough for me.

comment Area of a lattice polygon in terms of its width
Thay gives us $area(M)\geq d^2/4$, it is worse than $g\geq d^2/{2\sqrt{3}}$

at least you should always distinguish real bundles (and you have diffeomorphism here) and complex ones (here you have Chern classes)
