Levi-spherical Schubert varieties

Yibo Gao, Reuven Hodges, Alexander Yong

We prove a short, root-system uniform, combinatorial classification of Levi-spherical Schubert varieties for any generalized flag variety $G / B$ of finite Lie type. We apply this to…

On the minimal power of $q$ in a Kazhdan-Lusztig polynomial

Christian Gaetz, Yibo Gao

For $w$ in the symmetric group, we provide an exact formula for the smallest positive power $q^{h (w)}$ appearing in the Kazhdan-Lusztig polynomial $P_{e, w} (q)$ . We also provide a t…

Realizable Standard Young Tableaux

Igor Araujo, Alexander E. Black, Amanda Burcroff +3

Given two vectors $u$ and $v$ , their outer sum is given by the matrix $A$ with entries $A_{ij} = u_{i} + v_{j}$ . If the entries of $u$ and $v$ are increasing and sufficiently gener…
