On two notions of total positivity for generalized partial flag varieties of classical Lie types

Grant Barkley, Jonathan Boretsky, Christopher Eur +1

For Grassmannians, Lusztig's notion of total positivity coincides with positivity of the Plucker coordinates. This coincidence underpins the rich interaction between matroid theory…

Polyhedral and Tropical Geometry of Flag Positroids

Jonathan Boretsky, Christopher Eur, Lauren Williams

A flag positroid of ranks $r := (r_{1} < \dots < r_{k})$ on $[n]$ is a flag matroid that can be realized by a real $r_{k} \times n$ matrix $A$ such that the $r_{i} \times r_{i}$ mino…
