Recovering the hyperdefinable group action in the group configuration theorem
Published online by Cambridge University Press: 12 March 2014
Abstract
In this paper, we continue the construction done in [3], so that under model-4-CA or 4-CA, given a bounded quadrangle C induced from a group configuration, we build a canonical hyperdefinable homogeneous space equivalent toC. When C is principal, we can choose the homogeneous space principal as well.
