# Layered Mereotopology

Maureen Donnelly

*Proceedings of the Eighteenth International Joint Conference on Artificial Intelligence*, pages 1269-1273.

## Abstract

In fields such as medicine, geography, and mechanics, spatial reasoning involves reasoning about entities-for example cavities and invading particles-that may coincide without overlapping. The purpose of this paper is to develop a mereotopology for domains that include coincident entities, such as material objects, holes, geopolitical entities and spatial regions. In addition , I construct mathematical models of this mereotopology in which nontrivial coincidence relations are defined.
