495. Lynn Scow
Indiscernibles, EM-types, and Ramsey Classes of Trees

Submission date: 14 August 2012


It was shown in \cite{sc12} that for a certain class of structures I, I-indexed indiscernible sets have the modeling property just in case the age of I is a Ramsey class. We expand this known class of structures from ordered structures in a finite relational language to ordered, locally finite structures which isolate quantifier-free types by way of quantifier-free formulas. As a corollary, we obtain a new Ramsey class of finite trees.
