History Probability Theory and Related Fields was founded in 1962 under the title 'Zeitschrift für Wahrscheinlichkeitstheorie und verwandte Gebiete'. The first Managing Editor was L. Schmetterer who worte thus in the first issue: "Until abouto 30 years ago the theory of probability and its applications were somewhat isolated mathematical disciplines. Then following a period of remarkable development that is not yet completed by any means probability theory became an important domain of mathematics intimately connected with other domains especially with analysis and number theory. In addition it leads a life of its own all by itself and in its manifold applications. The founding Managing Editor was succeeded by K. Krickeberg in 1971 and by H. Rost in 1985. The main title of the journal was adapted into English in 1986 beginning with Volume 71. Subsequent Managing Editors are O. Kallenberg (1991) E. Bolthausen (1994) and G. Grimmett (2000). Of the founding Editors K.L. Chung K. Krickeberg and L. Schmetterer remain active. Aims and scope Probability Theory and Related Fields publishes research papers in modern probability theory its relations to analysis geometry and other areas in mathematics and its various fields of application. Thus subjects of interest include: statistical mechanics ergodic theory mathematical biology filtering theory mathematical statistics theoretical computer science optimization and control stochastic geometry and stochastic algorithms. The main languages of publication are English French and German. Submission of articles Articles may be submitted to the Editor who is most closely concerned with the subject matter of the paper. Articles may also be submitted directly to the Managing Editor. Authors should provide an e-mail address and/or fax number as well as a full postal address. Articles may be submitted electronically preferably as postscript or pdf files. Authors are responsible for providing electronic files which may be viewed without undue difficulty. Instructions for authors are given at the back of each issue. They can also be found at
