What s the struture of (2,2,0) type algebra

Dates
The phrasing quasi-bialgebras are a generalization of bialgebras, which were defined by the Ukrainian mathematician Vladimir Drinfeld in 1990 is ambiguous, since "which" might refer to bialgebras rather than to quasi-bialgebras. However more importantly the date seems wrong, if the reference is correctly dated as 1989. Tautological tau (talk) 17:27, 22 May 2013 (UTC)
