(Symmetry, Integrability and Geometry: Methods and Applications) is a good math journal, where by "good" I mean "not evil". It's open access, free to authors, links to the arXiv version, puts the official published version on the arXiv, etc. ...
It's really very nice. But one has fund so much niceness somehow. Here's a letter I got from them...
Dear SIGMA authors,
We would like to thank you for co-operation with the journal
SIGMA (Symmetry, Integrability and Geometry: Methods and Applications)http://www.emis.de/journals/SIGMA/
SIGMA is being published for nine years, and its current impact factor is 1.299.
SIGMA does not charge its readers for access, and despite this does
not charge authors for publication (i.e., it is no-fee open-access journal).
Moreover, SIGMA is not supported financially on a regular basis by any entity
(organization, foundation, fund, etc.) in Ukraine or abroad, including
the National Academy of Sciences of Ukraine, where the Editorial Office works.
Therefore, the journal has no revenue and steady sources of funding
whatsoever, and operates solely on the basis of the good will efforts
of its editors. All editorial work, including, but not limited to, the
copyediting, is done by volunteers free of charge.
SIGMA has no geographical concentration - its authors come
from 75 countries (USA 12.9%, Russia 8.1%, Japan 7.7%, France
6.7%, Italy 5.6%, Germany 4.3%, Spain 4.2%, UK 4,2%, Ukraine 4.0%,
Canada 3.8%, Mexico 3,7%, Australia 2.4%, Belgium 2.4%, Brazil
2,1%, other countries 28,0%), and so it actually belongs to all mathematical
In principle, we can see three ways for funding of journal:
1) charging readers (subscription without open access);
2) charging authors to keep open access;
3) finding sponsors.
From the time of founding of the journal in 2005 until now we consistently avoided
resolving to first two options, and we would like to maintain this
position further on. But to do that we would need to find some
As a first examples of such funding, we have received one-time
supports from the University Library of the Radboud University
Nijmegen (EUR 3000) and from Sociedad Mexicana de Fisica (USD 3500).
The relevant acknowledgments were published at the bottom of the main
page of the journal. But that covers only a small part of our costs.
If you would like to help in supporting, please contact in this respect
your university, professional societies or funds in your country.
Any amount would be a substantial support to our project.
We hope for your assistance and for any suggestions related to
