A complex semisimple Lie group carries a Poisson–Lie structure associated with a solution of the classical Yang–Baxter equation, parametrized by a Belavin–Drinfeld triple and conti…

Let $\mathfrak{g}=\mathfrak{sl}(n)$, let $\tau$ be a Belavin–Drinfeld triple, and suppose that $r^0=t^0/2+\tilde{r}^0\in\mathfrak{h}\otimes\mathfrak{h}$ is $\tau$-admissible. Defin…
