-
- Fixed Point Semantics is often used for the kind of Denotational Semantics
- which is based on Domain Theory and where one does not require the
- semantics in some sense to be computable (ie. based on the lambda calculus).
-
- Fixed Point Semantics is used heavily in Abstract Interpretation where neither
- the Standard Semantics (often in the form of a Collecting Semantics) or
- the Abstract Semantics correspond to lambda terms. They do, however,
- make perfect sense in Domain Theory.
