Procedural languages are generally well understood and their formal foundations cast in the forms of various lambda-calculi. For object- oriented languages however the situation is not as clear-cut. In this book the authors propose and develop a different approach by developing object calculi in which objects are treated as primitives. Using object calculi,the authors are able to explain both the semantics of objects and their typing rules and demonstrate how to develop all of the most important concepts of object-oriented programming languages: self, dynamic dispatch, classes, inheritance, protected and private methods, prototyping, subtyping, covariance and contravariance, and method specialization. Many researchers and graduate students will find this an important development of the underpinnings of object-oriented programming.

This book constitutes the thoroughly refereed post-conference proceedings of the 8th International Symposium on Trustworthy Global Computing, TGC 2013, held in Buenos Aires, Argentina, in August 2013. The 15 revised full papers presented together with 3 invited talks were carefully reviewed and selected from 29 submissions. The papers cover a wide range of topics in the area of global computing and safe and reliable computation. They are organized in topical sections on security, π-calculus, information flow, models, specifications and proofs and quantitative analysis.

This volume contains the papers presented at CONCUR 2005, the 16th - ternational Conference on Concurrency Theory. The purpose of the CONCUR series of conferences is to bring together researchers,developers, and students in order to advance the theory of concurrency and to promote its applications. This year’s conference was in San Francisco, California, from August 23 to August 26. We received 100 submissions in response to a call for papers. Each subm- sionwasassignedto at leastthreemembers ofthe ProgramCommittee; in many cases, reviews were solicited from outside experts. The ProgramCommittee d- cussed the submissions electronically, judging them on their perceived imp- tance, originality, clarity, and appropriateness to the expected audience. The Program Committee selected 38 papers for presentation. Because of the format of the conference and the high number of submissions, many good papers could not be included. Although submissions werereadand evaluated, the papers that appear in this volume may di?er in form and contents from the corresponding submissions. It is expected that many of the papers will be further revised and submitted to refereed archival journals for publication.

This book constitutes the refereed proceedings of the Third International Symposium on Theoretical Aspects of Computer Software, TACS'97, held in Sendai, Japan, in September 1997. The book presents 20 revised full papers selected from a total of 46 submissions. Also included are seven invited papers by internationally leading scientists. Among the topics addressed are action calculi, polymorphisms, type theory, lambda calculi, refinement, finite transition systems, model checking, process algebras, logical frameworks, higher-order logics, etc.
