Papers (2010 - )
'Notions around tree property 1' (with H-J. Kim), Annals of Pure and Applied Logic, 162 (2011) 698-709. Erratum: Kim-independence in each example of Example 0.1 satisfies all the basic axioms and type-amalgamation of Lascar types, except base monotonicity. See the paper below "Independence over arbitrary sets in NSOP1 theories."
'Tree indiscernibilities, revisited' (with H-J. Kim and L. Scow), Archive for Math. Logic, 53 (2014) 211-232.
'The Lascar group, and the strong types of hyperimaginaries', Notre Dame Journal of Formal Logic, 54 (2013) 497-507.
'A classification of 2-chains having 1-shell boundaries in rosy theories' (with SunYoung Kim and Junguk Lee), J. of Symbolic Logic, 80 (2015) 322-340. Erratum - The fixed strong type p should be a type of an algebraically closed tuple (over its parameter), since each vertex of simplices in p are defined to be an algebraically closed set.
'Transitivity, lowness, and ranks in NSOP1 theories' (with A. Chernikov and N. Ramsey), in preparation. We study consequences of transitivity of Kim-independence over sets in NSOP1 theories. In particular we show that Lascar types are strong types in low NSOP1 theories with nonforking existence, extending S. Buechler's result on low simple theories.
