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.","doi":null,"url":"https://ijcai.org/proceedings/2003/180","pdf":"https://ijcai.org/proceedings/2003/0180.pdf","markdown":"https://ijcai.org/proceedings/2003/180.md","bibtex":"https://ijcai.org/proceedings/2003/bibtex/180","volume":{"slug":"2003","title":"Proceedings of the Eighteenth International Joint Conference on Artificial Intelligence","short_title":"IJCAI 2003","url":"https://ijcai.org/proceedings/2003/","year":2003,"location":"Acapulco, Mexico","dates":"","editors":"Georg Gottlob","isbn":"","publisher":"International Joint Conferences on Artificial Intelligence","doi_prefix":""},"section":null,"track":"","number":180,"pages":{"first":1269,"last":1273},"keywords":[],"videos":[],"references":[],"license_note":"Copyright International Joint Conferences on Artificial Intelligence."}
