Submission Guidelines
I. Editorial information
To be published in the Tohoku Mathematical Journal, a paper must be correct, new, nontrivial, and significant. Further, it must be well written and of interest to a substantial number of mathematicians.
A Consent to Copyright Agreement is required before a paper will be published in this journal. By submitting a paper to this journal, authors certify that the results have not been submitted to nor are they under consideration for publication by another journal, conference proceedings, or a similar publication.
II. Preparation of manuscripts
Articles submitted for publication should be written in English, French or German.
The Tohoku Mathematical Journal encourages authors to prepare manuscripts in LaTeX2e, but other versions of TeX are also acceptable. For the preamble for specifying the documentstyle options of LaTeX2e, see the section VII below.
Footnotes should be reduced to a minimum. References should be precise, unambiguous and intelligible. Author's department, university and its location should be written at the end of the manuscript.
For electronic submission, authors should send the pdf file of their
manuscript, along with its TeX source file, to
.
The corresponding author should also be designated with full postal address.
If you want to submit by post, please send two hard copies of the manuscript to the following address by airmail. Handwritten manuscripts are not accepted. Authors are requested to submit the TeX source file of the final version of manuscripts when their papers are accepted for publication.

III. Abstract and 2020 MSC numbers
The Tohoku Mathematical Journal requires each paper in it to have an abstract as well as 2020 Mathematics Subject Classification (MSC) numbers, to facilitate its reviewing and inclusion in databases for electronic information retrieval.
The purpose of an abstract is to indicate to the reader the main topics treated in the paper so that the reader can decide quickly if the paper is of further interest. In view of its eventual inclusion in databases, mathematical symbols and formulas should not be used in an abstract. (In this respect, it is also desirable not to have mathematical symbols and formulas in the title as well.)
The 2020 Mathematics Subject Classification scheme was completed jointly by the Mathematical Reviews and the Zentralblatt für Mathematik. In this scheme,
precisely one primary classification number
and
none or several secondary classification numbers
are to be printed as a footnote on the first page of each paper. For example,
2020 Mathematics Subject Classification. Primary 14M25; Secondary 14F40, 32S60.
It is requested that the authors themselves assign the classification numbers for greater accuracy.
A full list of the 2020 Mathematics Subject Classification numbers, with a list of changes and conversion tables, is available electronically on eMATH of the American Mathematical Society.
IV. Illustrations
Those authors who submit papers with illustrations to the Tohoku Mathematical Journal are requested to keep the following in mind:
 1. All illustrations in one paper should be consecutively numbered as Figure 1, Figure 2, etc.
 2. The text should be independent of the actual placement of the illustrations: For instance, never write sentences like ``The graph of y=f(x) is as follows''. Instead, write ``The graph of y=f(x) is as in Figure 2''. Parenthetical references like ``(See Figure 2)'' may also be convenient. Although the printer will try to put each illustration as close as possible to the text reference to it, enough space may not be available on the page when the paper is actually typeset.
 3. Write the figure number (for example, Figure 2) in the margin of each drawing and its copy. Write, for instance, ``Figure 2'' also in the margin of the manuscript at the best place for it to be placed.
V. Proofs
Authors ordinarily receive only galley proofs. Stylistic changes in proofs must be avoided as possible. Authors will be charged for excessive corrections.
VI. Reprints
Each author receives 50 reprints gratis, postage prepaid. Joint authors receive 50 altogether. Additional reprints may be purchased if desired.
VII. Preamble for LaTeX2e
Please use the following preamble for specifying the documentstyle options.
