The Ax-Kochen-Ershov principles via the higher valued hyperfield
Junguk Lee
In this paper, we concern the model theory of finitely ramified henselian valued fields via higher valued hyperfields. Most of all, we provide a number of Ax-Kochen-Ershov Theorems…
Geometric stability theory for -structures
Junguk Lee, Michael Cohen, Phillip Wesolek
We introduce a notion of -structures which are certain locally compact group actions and prove some counterparts of results on Polish structures(introduced by Krupinski in \cite…
Non-commutative groupoids obtained from the failure of -uniqueness in stable theories
Byunghan Kim, SunYoung Kim, Junguk Lee
We construct a possibly non-commutative groupoid from the failure of -uniqueness of a strong type. The commutative groupoid constructed by John Goodrick and Alexei Kolesnikov in…
A classification of 2-chains having 1-shell boundaries in rosy theories
Byunghan Kim, SunYoung Kim, Junguk Lee
We classify, in a non-trivial amenable collection of functors, all 2-chains up to the relation of having the same 1-shell boundary. In particular, we prove that in a rosy theory, e…
