  1. Renato H. L. Pedrosa & Antonio M. A. Sette (1988). A Representation Theorem for Languages with Generalized Quantifiers Through Back-and-Forth Methods. Studia Logica 47 (4):401 - 411.score: 2010.0
    We obtain in this paper a representation of the formulae of extensions ofL by generalized quantifiers through functors between categories of first-order structures and partial isomorphisms. The main tool in the proofs is the back-and-forth technique. As a corollary we obtain the Caicedo's version of Fraïssés theorem characterizing elementary equivalence for such languages. We also discuss informally some geometrical interpretations of our results.
