The focus of this workshop was the development of mathematically-based techniques of formal specification of system behaviour, and the systematic development of implementations. The aim is to produce correct, efficient implementations in a reliable fashion. Topics covered at the workshop include category theory, logic, domain theory, semantics, concurrency, specification and verification. The papers published here range from the purely theoretical to practical applications.

Coordination, considered abstractly, is an ubiquitous notion in computer science: for example, programming languages coordinate elementary instructions; operating systems coordinate accesses to hardware resources; database transaction schedulers coordinate accesses to shared data; etc. All these situations have some common features, which can be identified at the abstract level as “coordination mechanisms”. This book focuses on a class of coordination models where multiple pieces of software coordinate their activities through some shared dataspace. The book has three parts. Part 1 presents the main coordination models studied in this book (Gamma, LO, TAO, LambdaN). Part 2 focuses on various semantics aspects of coordination, applied mainly to Gamma. Part 3 presents actual implementations of coordination models and an application.

This Festschrift volume is published in honor of Hanne Riis Nielson and Flemming Nielson on the occasion of their 60th birthdays in 2014 and 2015, respectively.

Static analysis allows us to determine aspects of the dynamic behavior of p- grams and systems without actually executing them. Traditionally used in - timizing compilers, static analysis is now also used extensively in veri?cation, software certi?cation and semantics-based manipulation. The research com- nity in static analysis covers a broad spectrum from foundational issues - new semantic models of programming languages and systems - through to practical tools.TheseriesofStatic AnalysisSymposia hasservedasthe primaryvenue for presentation and discussion of theoretical, practical and application advances in the area. This volume contains the papers accepted for presentation at the 12th Int- national Static Analysis Symposium (SAS 2005) which was held 7-9 September 2005 at Imperial College London. A total of 66 papers were submitted; the Program Committee held an online discussion which led to the selection of 22 papers for presentation. The selection was based on scienti?c quality, originality and relevance to the scope of SAS. Every paper was reviewed by at least 3 PC members or external referees.This volume also includes abstracts of talks given by the two invited speakers: Samson Abramsky FRS (University of Oxford) and Andrew Gordon (Microsoft Research, Cambridge). OnbehalfoftheProgramCommittee,theProgramChairwouldliketothank all of the authors who submitted papers and all of the external referees for their careful work in the reviewing process. The Program Chair would also parti- larly like to thank Igor Siveroni who provided local support for the conference management system and who helped in organizing the structure of this volume.

This book constitutes the refereed proceedings of the First International Conference on Coordination Languages and Models, COORDINATION '96, held in Cesena, Italy in April 1996. Over the last few years, a new class of models, formalisms, and mechanisms for describing concurrent and distributed computations has emerged. A characteristic feature of these coordination languages and models is that they are based on (generative) communication via a shared data space. The 21 revised full papers presented were selected from a total of 78 submissions; also included are three invited papers and 10 posters. All in all, these papers report the state of the art in this young and active area of research and development.

This book constitutes the refereed proceedings of the 7th European Symposium on Programming, ESOP'98, held as part of the Joint European Conferences on Theory and Practice of Software, ETAPS'98, in Lisbon, Portugal, in March/April 1998. This volume presents 17 revised full papers selected from a total of 59 submissions; also included is one invited paper. Among the issues addressed are software specification and verification, programming paradigms, semantics for formal development and implementation, program analysis, program transformation, etc.

Program analysis concerns static techniques for computing reliable approximate information about the dynamic behaviour of programs. Applications include compilers (for code improvement), software validation (for detecting errors in algorithms or breaches of security) and transformations between data representation (for solving problems such as the Y2K problem). This book is unique in giving an overview of the four major approaches to program analysis: data flow analysis, constraint based analysis, abstract interpretation, and type and effect systems. The presentation demonstrates the extensive similarities between the approaches; this will aid the reader in choosing the right approach and in enhancing it with insights from the other approaches. The book covers basic semantic properties as well as more advanced algorithmic techniques. The book is aimed at M.Sc. and Ph.D. students but will be valuable also for experienced researchers and professionals.
