Set theories are traditionally based on first-order logic. We show that in a constructive setting, basing a set theory on a dependent logic yields many benefits. To this end, we...
We consider the problem of providing formal support for working tract syntax involving variable binders. Gabbay and Pitts have shown in their work on Fraenkel-Mostowski (FM) set th...
We present a foundational theory of software system reliability based on components. The theory describes how component developers can design and test their components to produce ...
Starting from a logic which speci es how to make deductions from a set of sentences (a ` at theory'), a way to generalise this toa partiallyordered bag ofsentences (a `struct...
Interface theories have been proposed to support incremental design and independent implementability. Incremental design means that the compatibility checking of interfaces can pr...
