Higher rank classical analogs of the Askey-Wilson algebra from the $s l_{N}$ Onsager algebra

Pascal Baseilhac, Nicolas Crampe, Rodrigo A. Pimenta

The $s l_{N}$ -Onsager algebra has been introduced by Uglov and Ivanov in 1995. In this letter, a FRT presentation of the $s l_{N}$ -Onsager algebra is given, its current algebra and commu…

New D_{n+1}^(2) K-matrices with quantum group symmetry

Rafael I. Nepomechie, Rodrigo A. Pimenta

We find new families of solutions of the $D_{n + 1}^{(2)}$ boundary Yang-Baxter equation. The open spin-chain transfer matrices constructed with these K-matrices have quantum group s…
