We study revision programming, a logic-based mechanism for enforcing constraints on databases. the central concept of this approach is that of a justified revision based on a revision program. We show that for any pro...

We place simple axioms on an elementary topos which suffice for it to provide a denotational model of call-by-value PCF with sum and product types. the model is synthetic in the sense that types are interpreted by the...

A new decision procedure for the existential fragment of ordering constraints expressed using the recursive path ordering is presented. this procedure is nondeterministic and checks whether a set of constraints is sol...

the connection between some modularity properties and interpolation is revisited and restated in a general `logic-independent' framework. the presence of uniform interpolants is shown to assist in certain proof obligations, which suffice to establish the composition of refinements. the absence of the desirable interpolation properties from many logics that have been used in refinement, motivates a thorough investigation of methods to expand a specification formalism orthogonally, so that the critical uniform interpolants become available. A potential breakthrough is outlined in this paper.
