## Submission

A manuscript should be sent in pdf format via e-mail to kmj-ed(at)math.titech.ac.jp.
It must be new, correct and significant. Further, it must be of interest to a substantial number of readers.

## Manuscript preparation

Papers submitted for publication should be well written in English. The first page must include a title, name(s) of author(s), abstract, keywords and phrases, 2020 MSC numbers (one primary number and possibly a few secondary numbers), and a proposed running head (less than 60 characters including spaces). The last page must include postal and e-mail addresses of all authors.

All illustrations should be numbered. Any lettering should be large and bold enough to be legible.

References must be arranged in alphabetical order
as in the following style:

[1] D. E. Blair, S. Ishihara and G. D. Ludden, Projectable almost complex contact structures, Kodai Math. J. **1** (1978), 75-84.

[2] T. Homma and T. Minagawa, Vector-group in real Euclidean space, Kodai Math. Sem. Rep. **1** (1949), 19-20.

[3] K. Yano and S. Bochner, Curvature and Betti numbers, Annals of mathematics studies **32**, Princeton University Press, Princeton, N. J., 1953.

We welcome manuscripts prepared in TeX (LaTeX, AMS-TeX, etc.). When a paper written in TeX is accepted, the author(s) will be requested to send the source file to the KMJ office (kmj-ed(at)math.titech.ac.jp).

## Proofs
