At the suggestion of Professor Masaharu Morimoto, we organize the online conference for
the celebration for the retirement and the 70th birthday of

Professor Krzysztof M. Pawałowski

at Adam Mickiewicz University in Poznan, Poland.

The aim of this conference is
to present recent achievements in transformation group theory and related topics, and
to discuss perspectives of further researches.

　 We strongly recommend to participate in the conference "kpa70",
which is also a celebration conference for Professor Pawałowski.



　　 Dates : From 17 February 2021 to 19 February 2021.
　　 Venue : Tokyo University of Science. (Online via Zoom.)
　　 Registration : In order to register for the conference please e-mail Takao Satoh: takao[-at-]rs.tus.ac.jp. (Please replace [-at-] for @.)
