In December 2003, the First European Workshop on Multi-agent Systems (EUMAS) was held at the University of Oxford, UK. This workshop emerged from a number of related workshops and other scholarly activities that were taking place at both national and European levels, and was intended to provide a single recognised forum at which researchers and those interested in activities relating to research in the area of autonomous agents and multi-agent systems could meet, present (potentially preliminary) research results, problems, and issues in an open and informal but academic environment. Since then, yearly editions of the event were held in Barcelona (Spain), Brussels (Belgium), Lisbon (Portugal), Hammamet (Tunisia), Bath (UK), Agia Napa (Cyprus) and Paris (France). Since December 2009, the EUMAS workshops are supported by the European Association for Multiagent Systems (EURAMAS). Details about previous workshops can be found on the individual websites.

In 2011, the 9th European Workshop on Multi-agent Systems (EUMAS 2011) will take place in Maastricht (The Netherlands), hosted by the Department of Knowledge Engineering at Maastricht University.

We are proud to announce that the following researchers have kindly agreed to give an invited talk at EUMAS:
