Generalized Diagonals in Positive Semi-Definite Matrices
Robert Angarone, Daniel Soskin
We describe all inequalities among generalized diagonals in positive semi-definite matrices. These turn out to be governed by a simple partial order on the symmetric group. This pr…

Multiplicative Inequalities In Cluster Algebras Of Finite Type
Michael Gekhtman, Zachary Greenberg, Daniel Soskin
Generalizing the notion of a multiplicative inequality among minors of a totally positive matrix, we describe, over full rank cluster algebras of finite type, the cone of Laurent m…

Barrett-Johnson inequalities for totally nonnegative matrices
Mark Skandera, Daniel Soskin
Given a matrix , let denote the submatrix of determined by rows and columns . Fischer's Inequalities state that for each Hermitian positive sem…
