1050. Mike Haskel and Anand Pillay
On maximal stable quotients of definable groups in NIP theories

Submission date: 3 June 2016


For G a group definable in an NIP theory we prove that there is a smallest type-definable subgroup H of G such that the quotient G/H is stable. This generalizes the existence of G^{00}, the smallest type-definable subgroup of G of bounded index.
