Let (U,Uı) be a quasi-split quantum symmetric pair of arbitrary Kac–Moody type, where “quasi-split” means the corresponding Satake diagram contains no black node. We give a presentation of theıquantum groupUıwith explicitıSerre relations. The verification of newıSerre relations is reduced to some newq-binomial identities. Consequently,Uıis shown to admit a bar involution under suitable conditions on the parameters.
