Positivity and universal Plücker coordinates for spaces of quasi-exponentials

Steven N. Karp, Evgeny Mukhin, Vitaly Tarasov

A quasi-exponential is an entire function of the form $e^{cu}p(u)$, where $p(u)$ is a polynomial and $c\in \mathbb{C}$. Let $V = \langle e^{h_1u}p_1(u), \dots, e^{h_Nu}p_N(u) \ran…
