Morley rank

WebSep 18, 2024 · In order to prove that in a strongly minimal structure the Morley rank and the dimension are the same thing, I have to prove the following: Let X ⊂ N k a definable set and N a strongly minimal structure (i.e., every definable set is finite or cofinite and this is true also for elementary extensions of N ). WebMorley rank and, more generally, any Frobenius group of finite Morley rank splits. A Frobenius group is a group G together with a proper nontrivial malnormal subgroup H, i.e. a subgroup H such that H ∩Hg = {1} for all g ∈ G\H. (Note that if G is a bad group of finite Morley rank with Borel subgroup B then B < G is a Frobenius group.)
