Abstract:

We revise the hypothesis and the proof of Zilber's Indecomposability Theorem, for groups of finite Morley rank, following a version of this theorem by Wagner valid in the broader context of supersimple groups : it consists in attaching to any definable subset X of the group a definable subgroup e(X) which is easy to characterize (in the finite Morley rank case). We observe that old and new consequences of the theorem get a very smooth proof when we follow this new approach.
