This book is concerned with a number of theories that can be used for describ ing and analyzing systems of interacting components in case it is desirable or necessary to regard their time-dependent behavior. Society is becoming increasingly more dependent on complex computer based systems that are composed of several components that act concurrently and interact - to synchronize and communicate with each other. The com plexity of these systems arises to a great extent from the many ways in which their components can interact. The need that these components act and in teract on time as well...

This text constitutes the proceedings of the 10th International Conference on Concurrency Theory, CONCUR'99, held in Eindhoven, Netherlands in August 1999. The 32 revised full papers presented together with four invited contributions were selected from a total of 91 submissions.

The refereed proceedings of the 30th International Colloquium on Automata, Languages and Programming, ICALP 2003, held in Eindhoven, The Netherlands in June/July 2003.

The 84 revised full papers presented together with six invited papers were carefully reviewed and selected from 212 submissions. The papers are organized in topical sections on algorithms, process algebra, approximation algorithms, languages and programming, complexity, data structures, graph algorithms, automata, optimization and games, graphs and bisimulation, online problems, verification, the Internet, temporal...
