# Super version of a formula for Poisson brackets

I am reading a paper Lie superbialgebras and poisson-lie supergroups and trying to figure out how to compute a super Poisson bracket from a super $r$-matrix.

Let $G$ be a Lie supergroup and $\mathfrak{g}$ its Lie superalgebra. The formula (3) on page 158 of the paper Lie superbialgebras and poisson-lie supergroups is \begin{align} \{ \phi, \psi \} = \sum_{\mu, \nu \in B} (-1)^{|\phi||\nu|} r^{\mu \nu}( R_{\mu} \phi R_{\nu} \psi - L_{\mu} \phi L_{\nu} \psi ), \end{align} where $B$ is a homogeneous basis of $\mathfrak{g}$, $r = \sum_{\mu, \nu} r^{\mu \nu} \mu \otimes \nu$. This is the super Poisson bracket of $\mathcal{O}(G)$ which comes from $r$. This formula is very similar to the formula in the end of page 60 of a guide to quantum groups by Chari and Pressley.

Has the following formula \begin{align} \{T \overset{\otimes}{,} T\} = [T \otimes T, r] \end{align} on page 61 of "a guide to quantum groups" been translated to the super case? Are there some references about this? Thank you very much.
