Other Centres were invited to participate, with many other in the same research domain. An excellent cooperation has been built up between the RENYI Centre of Excellence and HUN-TING MA SZTAKI. Joint workshops and seminars are planned and maintained, and decision was made to plan for a joint larger international workshop too. The scientists from the 2 CoE-s have also joint publications and work together to prepare joint national and international (EU 6th FW) proposals.
