Association schemes on the Schubert cells of a Grassmannian

Yuta Watanabe

Let $F$ be any field. The Grassmannian $Gr (m, n)$ is the set of $m$ -dimensional subspaces in $F^{n}$ , and the general linear group $\mathrm{GL}_n(\mathbb{F}…

An Algebra Associated with a Flag in a Subspace Lattice over a Finite Field and the Quantum Affine Algebra $U_{q} (sl_{2})$

Yuta Watanabe

In this paper, we introduce an algebra $H$ from a subspace lattice with respect to a fixed flag which contains its incidence algebra as a proper subalgebra. We then estab…
