Abstract

We study the κ-Borel-reducibility of isomorphism relations of complete first order theories by using coloured trees. Under some cardinality assumptions, we show the following: For all theories T and T , if T is classifiable and T is unsuperstable, then the isomorphism of models of T is strictly above the isomorphism of models of T with respect to κ-Borel-reducibility.
