Münster Journal of Mathematics is a new mathematics journal devoted to the publication of research articles of high quality in all fields of pure and applied mathematics. It replaces the Schriftenreihe des Mathematischen Institutes Münster, founded in 1948 by H. Behnke and continued by R. Remmert, G. Maltese and C. Deninger. All articles are fully refereed. The volumes are indexed in the Mathematical Reviews and the Zentralblatt. The journal is published by the Mathematical Institutes of the Universität Münster. It is available both in eletronic and in printed form.
