Universal Plücker coordinates for the Wronski map and positivity in real Schubert calculus

Steven N. Karp, Kevin Purbhoo

Given a $d$ -dimensional vector space $V \subset C [u]$ of polynomials, its Wronskian is the polynomial $(u + z_{1}) \dots (u + z_{n})$ whose zeros $- z_{i}$ are the points of $\m…
