I would like to have some conditions that render a general Hankel matrix of the form \begin{pmatrix}a_1 & a_2 & a_3 &\cdots & a_n \\ a_2 & a_3 & a_4 & \cdots & a_{n+1} \\ a_3 & a_4 & a_5 & \cdots & a_{n+2} \\ \vdots & \vdots & \vdots & & \vdots \\ a_n & a_{n+1} & a_{n+2} & \cdots & a_{2n-1}\end{pmatrix} invertible. Ideally, these conditions are exclusive to Hankel matrices. Thanks.
