Workshop Announcement Categorical Algebra and Computation A Workshop in Honour of John Power on the occasion of his 60th Birthday 23rd December 2019 Research Institute for Mathematical Sciences, Kyoto University http://www.kurims.kyoto-u.ac.jp/~hassei/ajp60/ We are delighted to host a workshop in honour of John Power on the occasion of his 60th birthday at RIMS, Kyoto University. John, recently retired and now a honorary professor at Macquarie University, Sydney, is staying in Kyoto as a visiting professor of RIMS for the winter of 2019/2020. During his stay in Kyoto, John turns 60. John has made substantial contributions in category theory and its applications to computer science throughout his career. At the same time, he has been a wonderful teacher, mentor and friend to many of us, with his exceptional insights, kindness, and humour. Since the 1990's John has regularly visited Japan and worked with Japanese researchers, including several PhD students and young postdocs. John's presence has made great impact on Japanese research community of semantics of computation and related fields; John has co-authored a number of papers with young Japanese researchers and served as their mentor. This workshop will feature talks by John's friends and collaborators as well as young Japanese researchers who are under the influence of John's work in a broad sense. The speakers will include - Soichiro Fujii (Kyoto University) - Shin-ya Katsumata (NII, Tokyo) - Yoshiki Kinoshita (Kanagawa University) - Yuichi Komorida (NII, Tokyo) - Steve Lack (Macquarie University) - Ken Sakayori (University of Tokyo) and John Power. Registration Attendance is free. Please register at the workshop webpage http://www.kurims.kyoto-u.ac.jp/~hassei/ajp60/ so that we can estimate the number of participants. (We plan to supply tea, coffee and sweets during the break.) Venue The workshop will take place in the conference room 420 of the RIMS main building located in the North Campus of the university.
