Some algebra related to P- and Q-polynomial association schemes

A mild generalization of a Leonard pair called a tridiagonal pair, such that for each transformation all eigenspaces have dimension one.

Tridiagonal pairs and the quantum affine algebra $U_q({\hat {sl}}_2)$

Let $K$ denote a field and let $V$ denote a vector space over $K$ with finite positive dimension. By definition a Leonard pair on $V$ is a pair of linear transformations $A:V\to V$ and $A^*:V\to V$

Three mutually adjacent Leonard pairs

Spin Leonard pairs

Let $${\mathbb K}$$ denote a field, and let V denote a vector space over $${\mathbb K}$$ of finite positive dimension. A pair A, A* of linear operators on V is said to be a Leonard pair on V whenever

Leonard Pairs from 24 Points of View

Let K denote a field and let V denote a vector space over K with finite positive dimension. We consider a pair of linear transformations A: V → V and A*: V → V that satisfy both conditions below: (i)

LEONARD PAIRS AND THE ASKEY-WILSON RELATIONS

Let K denote a field and let V denote a vector space over K with finite positive dimension. We consider an ordered pair of linear transformations A:V→V and A*:V→V which satisfy the following two

Introduction to Leonard pairs

Two relations that generalize the $q$-Serre relations and the Dolan-Grady relations

We define an algebra on two generators which we call the Tridiagonal algebra, and we consider its irreducible modules. The algebra is defined as follows. Let K denote a field, and let $\beta, \gamma,

The Terwilliger Algebra of the Hypercube

An elementary proof that QD has the Q -polynomial property is given and T is a homomorphic image of the universal enveloping algebra of the Lie algebrasl2 (C).
