The Happy Connection between Rudi and Japanese Researchers

摘要

We would like here to summarize, in chronological order, the long-standing happy connection of Professor Rudolf Ahlswede to a Japanese research group, especially Japanese information theorists. The first contact with Japanese researchers took place at Grignano, in 1979; Te Sun and Kingo first met there Rudi on the occasion of IEEE ISIT. This is our first experience to visit outside Japan and to join an international symposium. Subsequently, on response to Rudi's kind invitation, Te Sun visited Bielefeld for three months in 1980.
