Expressibility of higher-order logics on relational databases : proper hierarchies : a dissertation presented in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Information Systems at Massey University, Wellington, New Zealand

Ferrarotti, Flavio Antonio Unknown Date (has links)
We investigate the expressive power of different fragments of higher-order logics over finite relational structures (or equivalently, relational databases) with special emphasis in higher-order logics of order greater than or equal three. Our main results concern the study of the effect on the expressive power of higher-order logics, of simultaneously bounding the arity of the higher-order variables and the alternation of quantifiers.
