General Information

The library of Mereology can be directly applied for a new specification of Tarski’ geometry of solids which has been proposed as a method for axiomatizing geometry using the notion of sphere (a.k.a. balls) as primitive instead of usual point based theories.  The file created by R. Dapoigny and P. Barlatier whose purpose is to propose a model of Tarki’s is expressed in Dependent Type Theory (Coq) and based on characteristic functions to formulate appropriate definitions. It focuses on proofs and usability of the model in formal ontologies. Our approach using mereological expressions for solids and points relies only on singular names to preserve first-order quantification and as such, it promotes the use of automated theorem provers such as those included with CoqHammer. A first geometric connective (the between relation) has already been added, leaving the user the ability to add its own connectives.
