　Aim and History

The aim of this journal is to publish rapidly original contributions to pure and applied mathematics. All papers are refereed.

Tsukuba journal of mathematics is a continuation of Science Reports of the Tokyo Bunrika Daigaku, Sect. A, Vol. 1-Vol.4, No 82(1930-1953) and Science Reports of the Tokyo Kyoiku Daigaku,Sect. A, Vol. 4, No.83-Vol. 13, No. 382 (1954-1977).

　Call for Papers

The main purpose of Tsukuba Journal of Mathematics is to promote research activities in pure and applied mathematics by publishing original research papers very rapidly. Selection for publication is on the basis of reports from referees commissioned by the editorial committee.
