Tree indiscernibilities, revisited

Logic 2013-12-25 v4

Abstract

We give definitions that distinguish between two notions of indiscernibility for a set {aηη\W}\{a_\eta \mid \eta \in \W\} that saw original use in \cite{sh90}, which we name \textit{\s\s-} and \textit{\n\n-indiscernibility}. Using these definitions and detailed proofs, we prove \s\s- and \n\n-modeling theorems and give applications of these theorems. In particular, we verify a step in the argument that TP is equivalent to TP1_1 or TP2_2 that has not seen explication in the literature. In the Appendix, we exposit the proofs of \citep[{App. 2.6, 2.7}]{sh90}, expanding on the details.
