Abstract. We survey some of the main results regarding the complexity and expressive power of Live Sequence Charts (LSCs). We first describe the two main semantics given to LSCs: a...
Abstract. In this paper we consider the relationship between refinement-oriented specification and specifications using a temporal logic. We investigate the extent to which one can...
Abstract. Church's Problem (1962) asks for the construction of a procedure which, given a logical specification on sequence pairs, realizes for any input sequence X an output...
We develop an explicit two level system that allows programmers to reason about the behavior of effectful programs. The first level is an ordinary ML-style type system, which conf...
Since Z, being a state-based language, describes a system in terms of its state and potential state changes, it is natural to want to describe properties of a specified system also...
