|Issue Date:||5-Feb-2001||Citation:||Kwek, L.C., Oh, C.H., Singh, K. (2001-02-05). A novel coproduct of suq (2) and its relation to XXZ spin chain model.

However, it is possible to define a twisted coproduct in this case that respects the algebra homomorphism. Application to XXZ spin chain model is discussed. © 2001 Elsevier Science B.V.||Source Title:||Physics Letters, Section A: General, Atomic and Solid State Physics||URI:||http://scholarbank.nus.edu.sg/handle/10635/95659||ISSN:||03759601||DOI:||10.1016/S0375-9601(00)00819-7|
