This book constitutes the refereed proceedings of the 7th FIP WG 2.2 International Conference, TCS 2012, held in Amsterdam, The Netherlands, in September 2012. The 25 revised full papers presented, together with one invited talk, were carefully reviewed and selected from 48 submissions. New results of computation theory are presented and more broadly experts in theoretical computer science meet to share insights and ask questions about the future directions of the field.

This volume contains the proceedings of the 10th International Conference on Concurrency Theory (CONCUR'99) held in Eindhoven, The Netherlands, 24-27 August 1999. ThepurposeoftheCONCURconferencesistobringtogetherresearchers, - velopersandstudentsinordertoadvancethetheoryofconcurrencyandpromote its applications. Interest in this topic is continuously growing, as a consequence oftheimportanceandubiquityofconcurrentsystemsandtheirapplications, and of the scienti?c relevance of their foundations. The scope of CONCUR'99 covers all areas of semantics, logics and veri?cation techniques for concurrent systems. A list of speci?c topics includes (but is not limited to) concurrency-related - pects of: models of computation and semantic domains, process algebras, Petri nets, event structures, real-time systems, hybrid systems, stochastic systems, - cidability, model-checking, veri?cation techniques, re?nement techniques, term and graph rewriting, distributed programming, logic constraint programming, object-oriented programming, typing systems and algorithms, case studies, and tools and environments for programming and veri?cation. The ?rst two CONCUR conferences were held in Amsterdam (NL) in 1990 and 1991, the following ones in Stony Brook (USA), Hildesheim (D), Uppsala (S), Philadelphia (USA), Pisa (I), Warsaw (PL) and Nice (F). The proceedings have appeared in Springer LNCS, as Volumes 458, 527, 630, 715, 836, 962, 1119, 1243, and 1466.

CONCUR'91 is the second international conference on concurrency theory, organized in association with the NFI project Transfer. It is a sequel to the CONCUR'90 conference. Its basic aim is to communicate ongoing work in concurrency theory. This proceedings volume contains 30 papers selected for presentation at the conference (from 71 submitted) together with four invited papers and abstracts of the other invited papers. The papers are organized into sections on process algebras, logics and model checking, applications and specification languages, models and net theory, design and real-time, tools and probabilities, and programming languages. The proceedings of CONCUR'90 are available asVolume 458 of Lecture Notes in Computer Science.
