**Journal
Overview.**
The Moscow Mathematical Journal (MMJ) is an international quarterly
published (paper and electronic) by the Independent University
of Moscow and the department of mathematics of the Higher
School of Economics, and distributed by the American
Mathematical Society. MMJ presents highest quality research
and research-expository papers in mathematics from all over
the world. Its purpose is to bring together different branches
of our science and to achieve the broadest possible outlook on
mathematics, characteristic of the Moscow mathematical school
in general and of the Independent University of Moscow in
particular.

An important specific trait of the journal is that it especially encourages research-expository papers, which must contain new important results and include detailed introductions, placing the achievements in the context of other studies and explaining the motivation behind the research. The aim is to make the articles — at least the formulation of the main results and their significance — understandable to a wide mathematical audience rather than to a narrow class of specialists.
