Center node: "modal logics of topological relations"
  Abstract: Logical formalisms for reasoning about relations between spatial regions play#N#a fundamental role in geographical information systems, spatial and constraint#N#databases, and spatial reasoning in AI. In analogy with Halpern and Shoham's#N#modal logic of time intervals based on the Allen relations, we introduce a#N#family of modal logics equipped with eight modal operators that are interpreted#N#by the Egenhofer-Franzosa (or RCC8) relations between regions in topological#N#spaces such as the real plane. We investigate the expressive power and#N#computational complexity of logics obtained in this way. It turns out that our#N#modal logics have the same expressive power as the two-variable fragment of#N#first-order logic, but are exponentially less succinct. The complexity ranges#N#from (undecidable and) recursively enumerable to highly undecidable, where the#N#recursively enumerable logics are obtained by considering substructures of#N#structures induced by topological spaces. As our undecidability results also#N#capture logics based on the real line, they improve upon undecidability results#N#for interval temporal logics by Halpern and Shoham. We also analyze modal#N#logics based on the five RCC5 relations, with similar results regarding the#N#expressive power, but weaker results regarding the complexity.
