Alternating-group rank conjecture for nonsolvable groups of finite Morley rank

About 2 years old · traced to

Let nn be a positive integer, let HH be a nonsolvable connected group of finite Morley rank, and suppose that Alt⁡(n)\operatorname{Alt}(n) acts definably and faithfully on HH by automorphisms. Alternating-group rank conjecture. For all sufficiently large nn,

n≤rk⁡H.n\leq \operatorname{rk} H.

The conjecture extends earlier work restricted to actions on groups of degenerate type. Its validity beyond that setting is posed as a key ingredient in the study of actions of alternating groups on nonsolvable groups of finite Morley rank.
