    Abstract:

    We investigate the notion of dilation of a propositional theory based
    on neighbourhoods in a generalized approximation space.We take both a semantic
    and a syntactic approach in order to define a suitable notion of theory dilation
    in the context of approximate reasoning on the one hand, and a generalized notion
    of forgetting in propositional logic on the other hand. We place our work in
    the context of existing theories of approximation spaces and forgetting, and show
    that neighbourhoods obtained by combining collective and selective dilation provide
    a suitable semantic framework within which to reason computationally with
    uncertainty in a classical setting.
