Abstract. We present a framework to extend the concept of type systems in programming languages to capture the dynamic interaction in component-based design, such as the communicat...
Abstract. We study the decidability and complexity of verification problems for timed automata over time intervals of fixed, bounded length. One of our main results is that time-bo...
This paper describes an effective verification procedure for imperative programs that handle (balanced) tree-like data structures. Since the verification problem considered is unde...
Embedded devices like smart cards can now run multiple interacting applications. A particular challenge in this domain is to dynamically integrate diverse security policies. In th...
We investigate the first-order theory of subtyping constraints. We show that the first-order theory of nonstructural subtyping is undecidable, and we show that in the case where a...
