Arrows Structures And Functors The Categorical Imperative

Arrows, Structures, and Functors

Dewey, Pragmatism and Economic Methodology

The first book that looks at Dewey and Economic Methodology, this intriguing new book contains contributions from economists and philosophers from a wide range of perspectives.

Algebraic Methods in Semantics

This book, which contains contributions from leading researchers in France, USA and Great Britain, gives detailed accounts of a variety of methods for describing the semantics of programming languages, i.e. for attaching to programs mathematical objects that encompass their meaning. Consideration is given to both denotational semantics, where the meaning of a program is regarded as a function from inputs to outputs, and operational semantics, where the meaning includes the sequence of states or terms generated internally during the computation. The major problems considered include equivalence relations between operational and denotational semantics, rules for obtaining optimal computations (especially for nondeterministic programs), equivalence of programs, meaning-preserving transformations of programs and program proving by assertions. Such problems are discussed for a variety of programming languages and formalisms, and a wealth of mathematical tools is described.
