Looking for stabilizers in NSOP$\_1$

In this work we study some examples of groups definable and type-definable in NSOP1 theories. We exhibit some behaviors of these groups that differ from the ones of simple groups. We take interest in the notions of generics and stabilizers, and define the Kim-stabilizer. We apply the notion of Kim-stabilizer and the stabilizer from Hrushovsky to the context of a group G definable in an NSOP1 field F satisfying some assumptions to show that there is a finite to one embedding of a type definable subgroup of G of bounded index into an algebraic group over F. We then show that definable groups in omega-free PAC fields satisfy these conditions.
