Twisted quantum affinizations and their vertex representations

Abstract: In this paper we generalize Drinfeld's twisted quantum affine algebras to construct twisted quantum algebras for all simply-laced generalized Cartan matrices and present their vertex representation realizations.2010 Mathematics Subject Classification. 17B37, 17B10.

“…The second Figure given above suggests us that the classical limit of U ( g µ ) should be certain Drinfeld type presentations of g[µ] constructed in Theorem 1.4. Indeed, in [CJKT1], by the quantum vertex operators technique, we construct a new quantum algebra U ( g µ ) when g is of simply-laced affine type and µ is nontransitive. Due to Theorem 1.4, we prove in § 6 that the classical limit of this quantum algebra is isomorphic to U( g[µ]).…”

“…It has been a question whether the twisted quantum affinization process introduced by Drinfeld can be generalized to diagram automorphisms of any symmetrizable Kac-Moody Lie algebra in a similar way to that of the untwisted case? In [9], by using vertex operator calculations, we generalized the twisted quantum affinization to a class of diagram automorphisms on simply-laced Kac-Moody Lie algebras. One notices that in general there exist nontrivial diagram automorphisms on non-simply-laced Kac-Moody Lie algebras that are not from finite types.…”

“…When µ = Id, it coincides with the quantum affinization algebra U (ĝ). When g is of simply-laced type, U (ĝ µ ) has been realized in [9] by vertex operators. Especially, in the case when g is of untwisted affine type X…”
