As its title promises, this book provides foundations for software specification and formal
software development from the perspective of work on algebraic specification. It …

We propose a core semantics for Dependent Haskell, an extension of Haskell with full-
spectrum dependent types. Our semantics consists of two related languages. The first is a …

Key ideas in programming language design and implementation explained using a simple
and concise framework; a comprehensive introduction suitable for use as a textbook or a …

For many application-level distributed protocols and parallel algorithms, the set of
participants, the number of messages or the interaction structure are only known at run-time …

We study a first-order functional language with the novel combination of the ideas of
refinement type (the subset of a type to satisfy a Boolean expression) and type-test (a …

Abstract Types express properties of programs; typechecking is specification checking.
However, the specifications expressed by types in conventional type systems are imprecise …

Beginning with BETA, a range of programming language mechanisms such as virtual
classes (class-valued attributes of objects) have been developed to allow inheritance in the …

Supplements have often been characterized as inert with respect to other content. But under
closer scrutiny, the data shows that supplements can take scope and participate in …

We study a first-order functional language with the novel combination of the ideas of
refinement type (the subset of a type to satisfy a Boolean expression) and type-test (a …

Abstract qPCF is a paradigmatic quantum programming language that extends PCF with
quantum circuits and a quantum co-processor. Quantum circuits are treated as classical data …
