Balbiani, P. and Kikot, Stanislav (2012) Sahlqvist theorems for precontact logics. In: Bolander, T. and Braner, T. and Ghilardi, S. and Moss, L.S. (eds.) Advances in Modal Logic. London, UK: College Publications, pp. 55-70. ISBN 9781848900684.
Abstract
Precontact logics are propositional modal logics that have been recently considered in order to obtain decidable fragments of the region-based theories of space introduced by De Laguna and Whitehead. We give the definition of Sahlqvist formulas to this region-based setting and we prove correspondence and canonicity results. Together, these results give rise to a completeness result for precontact logics that are axiomatized by Sahlqvist axioms.
