Domain equationsAll the semantic domains we use in this book are complete metric spaces. Most of them are defined as the solution of a recursive .. In this chapter, we discuss how to build and solve these domain equations.

Operational semanticsIn this chapter we study . semantic models. These models are defined by means of .. A labelled transition system is an abstract machine. It has a collection of configurations. These configurations are usually programs possibly decorated with some additional information, e.g., the values of the variables.

For example, in a fair execution of the parallel composition of the statements .[.; .] and .[.; .], with . not occurring in the terminating statements . and ., both . and . are executed infinitely often. This notion of fairness can easily be encoded by suitable use of an appropriate succes

Matthias Richter,Klaus Hurrelmann. The atomic actions of Chapter 4 are provided with a time stamp in the form of a nonnegative real number. The execution of the .[0.85] amounts to performing the atomic action .. This atomic action should be executed 0.85 seconds after its enabling. For example, upon execution of the statement .[1.0

Instead of using English to give a semantics to a programming language, one nowadays usually takes a more rigorous, mathematical, approach. A good example is the semantics of Standard ML given by Milner, Tofte, Harper, and McQueen.
