Non-commutative groupoids obtained from the failure of 3-uniqueness in stable theories
E-mail: , , .
Submission date: 29 April 2015.
We construct a possibly non-commutative groupoid from the failure of 3-uniqueness of a strong type. The commutative groupoid constructed by John Goodrick and Alexei Kolesnikov lives in the center of the groupoid.
A certain automorphism group approximated by the vertex groups of the non-commutative groupoids is suggested as a fundamental group of the strong type.
