Logical Patterns in Space 
Aiello, M.; van Benthem, J. 

In this paper, we revive the topological interpretation of modal
logic, turning it into a general language of patterns in space. In
particular, we define a notion of bisimulation for topological models
that compares different visual scenes. We refine the comparison by
introducing Ehrenfeucht-Fraisse' style games between patterns in
space. Finally, we consider spatial languages of increased logical
power in the direction of geometry.
