Faithful actions of braid groups by twists along ADE-configurations of spherical objects

Anya Nordskova, Yury Volkov

英文摘要:

We prove that the action of a generalized braid group on an enhanced triangulated categories, generated by spherical twist functors along an ADE-configuration of $ω$-spherical objects, is faithful for any integer $ω\neq 1$.
