Let ${\mathcal G}$ be a simple complex Lie group. A Belavin–Drinfeld triple is a triple $T=(\Gamma_1,\Gamma_2,\gamma)$, and write $k_T=|\Delta\setminus\Gamma_1|$. The associated to…

Belavin–Drinfeld cluster-structure conjecture. For any Belavin–Drinfeld triple $T=(\Gamma_1,\Gamma_2,\gamma)$ there exists a cluster structure $({\mathcal C}_T,\varphi_T)$ on…
