May 31, 2015 at 19:15	comment	added	GH from MO		Note that at $n=0$ the denominator $2^n-1$ is zero. Hence I updated the question and my response by omitting the $n=0$ term and changing $\frac{1}{1-z}$ to $\frac{z}{1-z}$.

May 31, 2015 at 18:48	comment	added	Duchamp Gérard H. E.		[the infinite Hankel matrix $[a_{i+j}]_{i,j\geq 0}$ has full rank] didn't you mean finite rank ?
