Bruhat operads II. Multiplicative structures

Gleb Koshevoy, Vadim Schechtman

The Bruhat operads from \cite{KS} are equipped with a structure of operads with multiplication.

On universal quadratic inequalities for minors of TNN matrices

Vladimir I. Danilov, Alexander V. Karzanov, Gleb A. Koshevoy

For positive integers $n, n^{'}$ , we give a combinatorial characterization for the set of quadratic inequalities on minors that are valid for all $n \times n^{'}$ totally nonnegative matri…

Bruhat operads

Gleb Koshevoy, Vadim Schechtman, with Appendix by Daria Poliakova

We describe some planar operads built from the higher Bruhat orders and show that they admit a multiplication.

Products of Kirillov-Reshetikhin modules and maximal green sequences

Yuki Kanakubo, Gleb Koshevoy, Toshiki Nakashima

We show that a $q$ -character of a Kirillov-Reshetikhin module (KR modules) for untwisted quantum affine algebras of simply laced types $A_{n}^{(1)}$ , $D_{n}^{(1)}$ , $E_{6}^{(1)}$ , $E_7^{…

Finest positroid subdivisions from maximal weakly separated collections

Gleb A. Koshevoy, Fang Li, Lujun Zhang

We adopt a formal and algebraic approach of Early \cite{E2} to study the positive tropical Grassmannian $Trop^{+} G r_{k, n}$ . Specifically, we deal with positroid subdi…
