Two-parameter quantum general linear supergroup and central extensions
Huafeng Zhang · arXiv (Cornell University) · 2016
The universal R-matrix of two-parameter quantum general linear supergroups is computed explicitly based on the RTT realization of Faddeev--Reshetikhin--Takhtajan. For the two-parameter quantum special linear supergroup associated with sl(2,2), a two-fold quasi-central extension is deduced from its Drinfeld--Jimbo realization.
