Hierarchies in independence logic

Authors: Pietro Galliani, Miika Hannula, and Juha Kontinen

Published in: LIPIcs, Volume 23, Computer Science Logic 2013 (CSL 2013)

Abstract

We study the expressive power of fragments of inclusion and independence logic defined either by restricting the number of universal quantifiers or the arity of inclusion and independence atoms in formulas. Assuming the so-called lax semantics for these logics, we relate these fragments of inclusion and independence logic to familiar sublogics of existential second-order logic. We also show that, with respect to the stronger strict semantics, inclusion logic is equivalent to existential second-order logic.

Inclusion Logic and Fixed Point Logic

Authors: Pietro Galliani and Lauri Hella

Published in: LIPIcs, Volume 23, Computer Science Logic 2013 (CSL 2013)

Abstract

We investigate the properties of Inclusion Logic, that is, First Order Logic with Team Semantics extended with inclusion dependencies. We prove that Inclusion Logic is equivalent to Greatest Fixed Point Logic, and we prove that all union-closed first-order definable properties of relations are definable in it. We also provide an Ehrenfeucht-Fraïssé game for Inclusion Logic, and give an example illustrating its use.
