comment An inequality for Fourier transform
It seems to me that the inequality follows from Plancherel inequality and the identity $\widehat{(-\Delta)^{-\alpha}f}=|x|^{-2\alpha}\widehat{f}$.

comment Better bound for Hardy-Littlewood maximal function
Testing your estimate on the characteristic of a ball, you see that when $\alpha\rightarrow+\infty$ you get a contradiction.

comment Elliptic Harnack inequality for 1D Schrodinger operator?
A Harnack inequality with constants depending on the radius may be found in Aizenman, M.; Simon, B. Brownian motion and Harnack inequality for Schrödinger operators.

comment Heat Equation on $[0,T] \times \mathbb{R}^n$
Duhamel formula could be the tool to prove such a result, by a contraction mapping argument. wiki.math.toronto.edu/DispersiveWiki/index.php/…

comment Converse to Chow's theorem in sub-riemannian geometry
Thank you very much! Unfortunately there are many "linguistic" differences between Control Theory texts and Subriemannian Geometry ones that may make not very appropriate to quote Jurdjevic book while discussing subriemannian geometry. Do you know of any "subriemannian" reference for the result I look for? Thank you very much!

comment Uncertainty principle on finite groups
You may know this, but Theorem 2 in arxiv.org/pdf/math/0608702v2.pdf shows that the kind of uncertainty principle you quoted holds for compact (in particular finite) groups, appropriately reworded.

comment What is Kirillov's method good for?
I think the paper linked above by Peter Dalakov was incorporated (and expanded) in Kirillov's book Lectures on the Orbit Method, which you may already know.
