「全国紙上数学談話会」と「四国数学紙上談話」について

Zenkoku Shijo Sugaku Danwakai is a Japanese mathematical journal published by the Department of Mathematics, Faculty of Sciences of Osaka University from 1934 to 1949. This mimeographed journal played an important role in the mathematical research announcements during World War II. Recently this journal was uploaded as pdf files at the HP of the Department of Mathematics of Osaka University. The URL is http://www. math.sci.osaka-u.ac.jp/shijodanwakai/. Shikoku Sugaku Shijo Danwa is also a Japanese mathematical mimeographed journal published by the Department of Mathematics, the Gakugei College of Tokushima University from 1951 to 1956. We have compared the authors, titles and contents of these journals and concluded that Shikoku Sugaku Shijo Danwa played a successive role to Zenkoku Shijo Sugaku Danwakai. In 2014, we have uploaded this mimeographed journal as pdf files at the HP of the Department of Mathematical Sciences of Tokushima University (http://www-math. ias.tokushima-u.ac.jp/). We must mention that many frontier results in those days are included in these journals, although they were written in Japanese.
