The noncommutative formal Galois group bijectivity conjecture

Let NCFL/k\mathcal{NCF}_{L/k} be the noncommutative formal deformation functor and let QG^3,q\widehat{QG}_{3,q} be the corresponding formal quantum Galois group; Proposition 6.8o gives a functorial injection

NCFL/kQG^3,q.\mathcal{NCF}_{L/k}\longrightarrow\widehat{QG}_{3,q}.

Noncommutative formal Galois group conjecture. If qq is not a root of unity, the injection in Proposition 6.8o is a bijection. Consequently,

NCFL/kQG^3,q.\mathcal{NCF}_{L/k}\simeq\widehat{QG}_{3,q}.

This conjecture identifies the noncommutative formal deformation functor with the formal quantum Galois group; the supplied text gives no resolution status.
