Can I read Schur positivity and Schur log-concavity on EtoBox?

Schur positivity and Schur log-concavity by Lam, Thomas; Postnikov, Alexander; Pylyavskyy, Pavlo is a scholarly article available to read on EtoBox.

What is Schur positivity and Schur log-concavity about?

We prove Okounkov's conjecture, a conjecture of Fomin-Fulton-Li-Poon, and a special case of Lascoux-Leclerc-Thibon's conjecture on Schur positivity and give several more general statements using a recent result of Rhoades and Skandera. An alternative proof of this result is provided. We also give an intriguing log-concavity property of Schur functions.
