Paper classification scheme (2003)

With effect from 1 January 2003 (volume 36), the following classification scheme will be introduced for research papers published in Journal of Physics A: Mathematical and General . We believe that this new scheme will help to clarify the journal's scope and enable authors and readers to more easily locate the appropriate section for their work. We also list below some more detailed subject areas which should help define each section heading. These lists are by no means exhaustive and are intended only as a guide to the type of papers we envisage appearing in each section. We acknowledge that no classification scheme can be perfect and that there are some papers which might be placed in more than one section. Whenever possible, we will respect the author's wishes on placement and undertake to inform authors when we feel that a different classification is more appropriate. We are happy to provide further advice on paper classification to authors upon request (please email jphysa@iop.org ). 1.
