Second Circular Professor Francesco Calogero of Rome University, one of the pioneers of the multi-particle quantum integrable systems, will visit Yukawa Institute for Theoretical Physics, Kyoto University from 15 to 20 July, 2005. On this occasion, a mini-Workshop for specialists and a YITP Colloquium for a wider audience are organised, on 19 July (Tuesday) and on 20 July (Wednesday), respectively.
