| dc.description | In this work we investigate several important aspects of the structure theory of the recently introduced quasi-Hopf superalgebras (QHSAs), which play a fundamental role in knot theory and integrable systems. In particular we introduce the opposite structure and prove in detail (for the graded case) Drinfeld's result that the coproduct $Δ' \equiv (S\otimes S)\cdot T\cdot Δ\cdot S^{-1}$ induced on a QHSA is obtained from the coproduct $Δ$ by twisting. The corresponding ``Drinfeld twist'' $F_D$ is explicitly constructed, as well as its inverse, and we investigate the complete QHSA associated with $Δ'$. We give a universal proof that the coassociator $Φ'=(S\otimes S\otimes S)Φ_{321}$ and canonical elements $α' = S(β),$ $β' = S(α)$ correspond to twisting the original coassociator $Φ= Φ_{123}$ and canonical elements $α,β$ with the Drinfeld twist $F_D$. Moreover in the quasi-triangular case, it is shown algebraically that the R-matrix $R' = (S\otimes S)R$ corresponds to twisting the original R-matrix $R$ with $F_D$. This has important consequences in knot theory, which will be investigated elsewhere. | |
