Hodge numbers for orbifolds of Calabi-Yau threefolds Fermat type and the Roan pairs
S. Aleshin, Sergey Aleshin, A. Belavin +3
The paper defines Roan's Hodge numbers for orbifolds of Ferm(a)‑type Calabi‑Yau threefolds, proves they reproduce the stringy Euler numbers via the Vafa formula, and relates the Bo…
Bruhat operads II. Multiplicative structures
Gleb Koshevoy, Vadim Schechtman
The Bruhat operads from \cite{KS} are equipped with a structure of operads with multiplication.
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.
Stability of Type A MirkoviÄ-Vilonen Polytopes under Minkowski Sum via Weak Separation
Gleb A. Koshevoy, Fang Li, Lujun Zhang
MirkoviÄ--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 add…
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…
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 . Specifically, we deal with positroid subdi…
