Hodge numbers for orbifolds of Calabi-Yau threefolds Fermat type and the Roan pairs
Sergey Aleshin, Alexander Belavin, Gleb Koshevoy
First, for orbifolds of Calabi-Yau threefolds of Fermat type, we define Roan's Hodge numbers. We prove, Theorem \ref{main} , that for all orbifols of Calabi-Yau threefolds Fermat t…
Stability of Type A Mirković-Vilonen Polytopes under Minkowski Sum via Weak Separation
Gleb A. Koshevoy, Fang Li, Lujun Zhang
Mirković--Vilonen (MV) polytopes play a key role in the representation theory of reductive algebraic groups, while the geometric behavior of prime MV polytopes under Minkowski addi…
Quaternities, correspondences, and tetrahedron equations (Summa tetralogiae)
Gleb Koshevoy, Vadim Schechtman, Alexander Varchenko
The aim of this note is: (a) to propose a generalization of tetrahedron equations from \cite{S} and of their solutions. Due to appearance of a larger number of parameters the -m…
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 , we give a combinatorial characterization for the set of quadratic inequalities on minors that are valid for all 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.
