In the process of interactive theorem proving one often works with incomplete higher order proofs. In this paper we address the problem of giving a correctness criterion for these ...
Hybrid is a system developed to specify and reason about logics, programming languages, and other formal systems expressed in rder abstract syntax (HOAS). An important goal of Hyb...
Interactions between agents in an open system such as the Internet require a significant degree of flexibility. A crucial aspect of the development of such methods is the notion o...
We define seal, an untyped call-by-value -calculus with primitives for protecting abstract data by sealing, and develop a bisimulation proof method that is sound and complete with...
Abstract. When designing an open system, there might be no implementation available for certain components at verification time. For such systems, verification has to be based on a...
