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…

Symmetric Toda, gradient flows, and tridiagonalization

Anthony M. Bloch, Steven N. Karp

The Toda lattice (1967) is a Hamiltonian system given by $n$ points on a line governed by an exponential potential. Flaschka (1974) showed that the Toda lattice is integrable by in…
