Interpreting mereotopological connection

This paper examines ten possible topological interpretations of connection and for each interpretation, identifies sufficient conditions under which a significant class spaces provides models General Extensional Mereotopology with Closure Conditions (GEMTC) in some key mereotopological ideas align their analogues. In particular, there is an interpretation the non-empty sets any symmetric topology are model GEMTC alignment between definitions (self-)connection, open closed entities, interior, exterior, closure, boundary.
