A skew group ring of $Z /2 Z$ over $U (sl_{2})$ , Leonard triples and odd graphs

Hau-Wen Huang, Chin-Yen Lee

We employ a skew group ring of $Z /2 Z$ over $U (sl_{2})$ to construct modules over the universal Bannai--Ito algebra. In addition, we give the conditions und…

Johnson graphs as slices of a hypercube and an algebra homomorphism from the universal Racah algebra into $U (sl_{2})$

Hau-Wen Huang, Chia-Yi Wen

From the viewpoint of Johnson graphs as slices of a hypercube, we derive a novel algebra homomorphism $♯$ from the universal Racah algebra $ℜ$ into $U (sl_{2})$ . We…

An imperceptible connection between the Clebsch--Gordan coefficients of $U_{q} (sl_{2})$ and the Terwilliger algebras of Grassmann graphs

Hau-Wen Huang

The Clebsch--Gordan coefficients of $U (sl_{2})$ are expressible in terms of Hahn polynomials. The phenomenon can be explained by an algebra homomorphism $♮$ from th…

The Clebsch--Gordan coefficients of $U (sl_{2})$ and the Terwilliger algebras of Johnson graphs

Hau-Wen Huang

The universal enveloping algebra $U (sl_{2})$ of $sl_{2}$ is a unital associative algebra over $C$ generated by $E, F, H$ subject to the relations \begin{ali…

A Connection Behind the Terwilliger Algebras of $H (D, 2)$ and $\frac{1}{2} H (D, 2)$

Hau-Wen Huang, Chia-Yi Wen

The universal enveloping algebra $U (sl_{2})$ of $sl_{2}$ is a unital associative algebra over $C$ generated by $E, F, H$ subject to the relations \begin{ali…

The Terwilliger algebra of the halved cube

Chia-Yi Wen, Hau-Wen Huang

Let $D \geq 3$ denote an integer. For any $x \in F_{2}^{D}$ let $w (x)$ denote the Hamming weight of $x$ . Let $X$ denote the subspace of $F_{2}^{D}$ consisting of all $x\in \m…
