Qualitative Spatial Logic over 2D Euclidean Spaces Is Not Finitely Axiomatisable

Du, Heshan; Alechina, Natasha

Abstract

Several qualitative spatial logics used in reasoning about geospatial data have a sound and complete axiomatisation over metric spaces. It has been open whether the same ax-iomatisation is also sound and complete for 2D Euclidean spaces. We answer this question negatively by showing that the axiomatisations presented in (Du et al. 2013; Du and Alechina 2016) are not complete for 2D Euclidean spaces and, moreover, the logics are not finitely axiomatisable.
