On Schubert varieties of complexity one

Eunjeong Lee, Mikiya Masuda, Seonjeong Park

Let $B$ be a Borel subgroup of $GL_{n} (C)$ and $T$ a maximal torus contained in $B$ . Then $T$ acts on $GL_{n} (C) / B$ and every Sc…

Unique toric structure on a Fano Bott manifold

Yunhyung Cho, Eunjeong Lee, Mikiya Masuda +1

We prove that if there exists a $c_{1}$ -preserving graded ring isomorphism between integral cohomology rings of two Fano Bott manifolds, then they are isomorphic as toric varieties.…

Poincare polynomials of generic torus orbit closures in Schubert varieties

Eunjeong Lee, Mikiya Masuda, Seonjeong Park +1

The closure of a generic torus orbit in the flag variety $G / B$ of type $A$ is known to be a permutohedral variety and its Poincare polynomial agrees with the Eulerian polynomial. I…

Grossberg-Karshon twisted cubes and hesitant jumping walk avoidance

Eunjeong Lee

Let $G$ be a complex simply-laced semisimple algebraic group of rank $r$ and $B$ a Borel subgroup. Let $i \in [r]^{n}$ be a word and let $\mathbf \ell = (\ell_1,\dots,\ell_n)…
