Domain Theory was originally introduced in early 1970's as a mathematical foundation for the semantics of programming languages, which provided the first maathematical model for functional programing languages. It soon became a main paradigm in the theoretical computer science. Since early 1990's, it has also found applications in various areas of mathematical computation ranging from representation of topological spaces, classical measure and integration theory, real number computation and computational geometry/geometric modeling to initial value problems and hybrid systems. These different applications have established Domain Theory as a major paradigm in developing data types for continuous variables and for exact computation where the object of approximation in different areas of computation can be obtained within the accuracy required by the user. In this workshop, some expository talks on the subject will be given and some of these applications will be presented and explored.
