The method combines mathematical rigor, due to the work of Dana Scott, with notational elegance, due to Strachey. The operational and denotational semantics of recursive quantum programs are defined. Here, the theory of quantum domains is also needed to deal with the denotational semantics. • The third part – Section 3.5 – presents an illustrative example showing how the Grover quantum search can be programmed in the language defined in this chapter.

"First book-length exposition of the denotational (or `mathematical' or `functional') approach to the formal semantics of programming languages (in contrast to `operational' and `axiomatic' approaches). Treats various kinds of languages, beginning with the pure-lambda-calculus and progressing through languages with states, commands, jumps, and assignments. This somewhat discursive account is a

Similarly, the denotational semantics of the sequential composition of commands can be given by the operation of composition of partial functions from states to states, as shown on slide 4. Denotational semantics is a methodology for giving mathematical meaning to programming languages and systems.

The method combines mathematical rigor, due to the work of Dana Scott, with notational elegance, due to Strachey. The basic idea of denotational semantics is, given a language L, define the meaning of L by supplying a valuation functionfor each construct.

Denotational semantics also leads to optimization directly: normalization-by-evaluation, or optimization by calculation rather than rewriting. This web page collects examples of applying the semantic, denotational approach to a variety of problems -- making a case for semantics. Denotational definitions for simple languages are simple.

The method combines mathematical rigor, due to the work of Dana Scott, with notational elegance, due to Strachey. In computer science, denotational semantics is an approach for providing mathematical meaning to systems and programming languages. In other words, denotational semantics is a formal technique for expressing the semantic definition of a programming language. The most successful system is denotational semantics which describes all the features found in imperative programming languages and has a sound mathematical basis. (There is still active research in type systems and parallel programming.) An important principle of denotational semantics is that the meaning of a program is determined from its text compositionally. This means that the meaning of a program must be de ned from the meanings of its parts, not something else, such as the text of its parts or the meanings of related programs obtained by syntactic operations.

It was developed by Christopher Strachey’s Programming Research Group at Oxford University in the 1960s. The method combines mathematical rigor, due to the work of Dana Scott, with notational elegance, due to Strachey. In 1986, Allyn and Bacon published my Denotational Semantics text, which I wrote while I was a post-doc in Edinburgh in 1982-83. The book sold steadily over the years, but Allyn and Bacon was purchased by William C. Brown, which was purchased by McGraw-Hill.
