Abstract: We explain construction of Darboux coordinates for generic symplectic leaves of the groupoid of unipotent upper triangular matrices using Fock-Goncharov coordinates for framed moduli space of flat connections and express the braid group action as a sequence of cluster mutations. This is a joint project with L. Chekhov. Language: English |
