### History

The Illinois Journal of Mathematics was founded in 1957 by R. Baer, J. L. Doob, A. Taub, G. Whitehead, and O. Zariski, and has quickly established itself as a preeminent journal of mathematics. The inaugural volume features papers of many of the world’s leading figures in the key areas of mathematics at the time: William Feller, Paul Levy, and Paul Malliavin in probability theory; Richard Bellman, R. P. Boas, Jack Hale, and Edwin Hewitt in analysis; Marvin Marcus, Olga Taussky, and Oscar Zariski in algebra; and Paul Erdos, L. J. Mordell, and John Tate in number theory. Since then, IJM has published many influential papers, most notably the proof of the Four Color Conjecture by K. Appel and W. Haken. Distinguished researchers such as J. Bourgain, A. Calderon, S. S. Chern, H. Kesten, and K. Uhlenbeck have served as editors of IJM.

### Publishing Philosophy

As a non-profit journal published by the Department of Mathematics at the University of Illinois at Urbana-Champaign, IJM aims to keep its costs low while maintaining the highest production and editorial standards, and to pass the savings on to subscribing institutions. At a subscription price of around 17 cents per page, IJM ranks as one of the least expensive journals in mathematics.

### Electronic Edition

Beginning with Volume 52 (2008), an electronic version of IJM is published at Project Euclid. The electronic version is restricted to subscribers beginning with Volume 54 (2010). The entire IJM archive (from Vol. 1, 1957) is available at Project Euclid.

### Editorial Policy

IJM strives to publish high quality research papers in all areas of mainstream mathematics that are of interest to a substantial number of its readers. Over the past several years, under an expanded editorial board, the journal has begun a serious effort to raise the standards of its papers, broaden its coverage, and increase its reputation in order to make it more attractive to authors and subscribers alike. The journal implemented a system of centralized electronic processing of papers, which has resulted in eliminating much of the administrative overhead involved in the traditional processing of papers, reducing the burden on editors, referees, and journal staff, and speeding up the publication process.

### Special Volumes

In 2004, IJM inaugurated a series of affordable monographs with publication of the Baer Volume, a collection of invited articles to mark the centenary of the birth of Reinhold Baer, one of the founders of IJM. A second volume in this series, the Doob Volume, was published in 2007, to honor the memory of Joseph Doob, a founding editor of IJM and a leading figure in twentieth century American mathematics. The next volume in this series was the Griffith Volume, published in 2008, which contains the proceedings of a Commutative Algebra Conference held in 2005 in honor of Phillip Griffith. A special volume in honor of Don Burkholder, a preeminent scholar and researcher in the field of probability, was published in 2010, and a collection of articles in honor of Paul Schupp, an iconic figure in Geometric Group Theory, was published as a special volume in 2011. The next volume published in the series, honoring John P. D’Angelo, a pioneer in advances in the field of several complex variables and highly regarded researcher, lecturer, expositor, and author, was published in 2012. The latest volume, to be released in summer 2017, honors Wolfgang Haken, whose most famous mathematical achievement (joint with Ken Appel), is his solution to the Four Color Problem in graph theory.
