The finite Morley rank analogue of Glauberman's theorem for twisted subgroups

Let GG be a connected group of finite Morley rank, and let LL be a definable uniquely 22-divisible twisted subgroup of Morley degree 11 such that

G=L.G=\langle L\rangle.

Here, a twisted subgroup is a subset closed under inverses and under the operation (x,y)xyx(x,y)\mapsto xyx, and uniquely 22-divisible means that every element has a unique square root in the relevant subgroup.

Finite Morley rank Glauberman conjecture. The group GG is solvable.

This is proposed as a finite Morley rank version of Glauberman's theorem, which proves solvability for groups generated by finite uniquely 22-divisible twisted subgroups. The authors note that it is not known whether every uniquely 22-divisible K-loop of finite Morley rank can be definably half-embedded into a group of finite Morley rank.
