(SI) Izmenično osrednjo razširitev q-Onsagerja generira q-Onsager skupaj z nekaterimi dodatnimi osrednjimi elementi. To postavlja vprašanje, na katerem namerava vodja projekta delati. Naš problem je: Ali lahko najdemo elemente v naši algebri T, ki niso v T, ampak komutirajo z vsem v T? Takšni elementi so lahko manjkajoči generatorji za izmenično centralno razširitev Q-Onsagerja ali U^+_q.
(EN) The alternating central extension of q-Onsager is generated by q-Onsager along with some extra central elements. This raises a question that the project leader plan to work on. Our problem is: Can we find any elements in our algebra T, that are not in T, but commute with everything in T? Such elements might be the missing generators for the alternating central extension of Q-Onsager or U^+_q.
