  title={Corresponding Regions in Euler Diagrams},

Euler diagrams use topological properties to represent settheoretical concepts and thus are ‘intuitive’ to some people. When reasoning with Euler diagrams, it is essential to have a notion of correspondence among the regions in different diagrams. At the semantic level, two regions correspond when they represent the same set. However, we wish to construct a purely syntactic definition of corresponding regions, so that reasoning can take place entirely at the diagrammatic level. This task is… CONTINUE READING
