With a hope of bridging the gap between Southeastern and Western European scientific community, the participants of the UNESCO sponsored Balkan Workshop BW2003 (Vrnjačka Banja, Serbia) came to a common agreement on the initiative for the creation of the Southeast European Network in Mathematical and Theoretical Physics (SEENET-MTP). The Network was a natural extension of the WIGV initiative – Scientists in Global Responsibility, launched by Julius Wess in 1999.
