First works were attempts to integrate space in economic analysis. Subsequently moved away towards formal representations of space and their analytical implications: application of graphs and networks theory and general topology in spatial economic theory. More recently, research has been devoted to the statement of a fuzzy economic spaces theory.
Mathematical tools are fuzzy subsets theory and their applications. The results are several contributions on imprecise economic universes and soft economic behaviour under fuzzy constraints (spatial partial equilibria and general equilibrium). Much of my work has been devoted to the history of spatial economic theory.
