Dow P. Hurst,Patricia H. Reggioodels of SDT and show that the domains in them yield models of ADT. On the other hand, for each model of ADT in a wide class we construct a model of SDT such that the domains in it provide a model of ADT which conservatively extends the original model.

A. S. Lewis,R. Heroux,F. Nolte,P. Robinson We obtain our result by giving a winning strategy for the duplicator in the Ajtai-Fagin Ehrenfeucht-Fraïssé Game. The result can be strengthened to obtain nondefinability for a larger class of graphs.

https://doi.org/10.1007/978-1-4615-2802-9uctors is associated to each term of the system whose unification gives the possible typings. We define a syntactic restriction on constructors which is enough to capture all the typability problems: the elementary calculus. We use these principal typed terms to prove that the higher order typings hierarchy collapse at the second level.
