Abstract. Software security can be ensured by specifying and verifying security properties of software using formal methods with strong theoretical bases. In particular, programs c...

We present a new labelled transition system (lts) for the ambient calculus on which ordinary bisimilarity coincides with contextual equivalence. The key feature of this lts is that...
We present a sound and complete method for reasoning about contextual equivalence in the untyped, imperative object calculus of Abadi and Cardelli [1]. Our method is based on bisim...
We present a sound and complete proof technique, based on syntactic logical relations, for showing contextual equivalence of expressions in a -calculus with recursive types and imp...
Interesting properties of programs can be expressed using contextual equivalence. The latter is difficult to prove directly, hence (pre-)logical relations are often used as a tool ...
We define and study bisimulation for proving contextual equivalence in an aspect extension of the untyped lambda-calculus. To our knowledge, this is the first study of coinductive...
This tutorial paper discusses a particular style of operational semantics that enables one to give a ‘syntax-directed’ inductive definition of termination which is very useful...
Abstract. Security properties are profitably expressed using notions of contextual equivalence, and logical relations are a powerful proof technique to establish contextual equiva...

The problems of contextual equivalence and approximation are studied for the third-order fragment of Idealized Algol with iteration (IA∗ 3). They are approached via a combination...
