PBW bases and centralisers for the -Onsager algebra
Haoran Zhu
We prove that, over an arbitrary field and whenever is not a root of unity, the Baseilhac--Kolb root vectors form a PBW basis of the -Onsager algebra for every total order o…

A new PBW basis for the alternating central extension of the -Onsager algebra
Haoran Zhu
We establish a new PBW basis for , the alternating central extension of the -Onsager algebra. Terwilliger showed that the alternating generators form a PBW basis i…
