Morley rank
WebThe Morley rank of a formula φ defining a definable (with parameters) subset S of M is an ordinal or −1 or ∞, defined by first recursively defining what it means for a formula to have … Webof finite Morley rank, namely the Cherlin-Zil’ber algebraicity conjecture which states that an infinite simple group of finite Morley rank is a linear algebraic group over an algebraically closed field. In the last fifteen years an increasing number of partial affirmative answers have been given to special cases of this conjecture.

WebAug 4, 2010 · Groups of finite Morley rank made their first appearance in model theory as binding groups, which are the key ingredient in Zilber's ladder theorem and in Poizat's explanation of the Picard-Vessiot theory. These are not just groups, but in fact permutation groups acting on important definable sets. WebMorley rank is algebraic. (Details, mixed and even type.) In the odd type case, the situation is less clear. G is algebraic; G has Prufer2-rank at most 2; G is a minimal simple group (in the sense that G has no proper definable connected simple sections); If G is tame, this can be
