Oberwolfach Preprints (OWP)

The MFO publishes a preprint series Oberwolfach Preprints (OWP), ISSN 1864-7596, which mainly contains research results related to a longer stay in Oberwolfach. In particular, this concerns the Research in Pairs Programme (RiP) and the Oberwolfach Leibniz Fellows (OWLF), but this can also include an Oberwolfach Lecture, for example.

A preprint can have a size from 1 - 200 pages, and the MFO will publish it on its website as well as by hard copy. Every RiP group or Oberwolfach Leibniz Fellow may receive on request 30 free hard copies (DIN A4, black and white copy) by surface mail.

The full copy right is left to the authors. The MFO only needs the right to publish it, e.g. on its website, as a documentation of the research work done at the MFO, which you are accepting by sending us your file.

In case of interest, please send a pdf file of your preprint by email to or , respectively. The file should be sent to the MFO within 12 months after your stay as RiP or OWLF at the MFO.

The preprint (and a published paper) should contain an acknowledgement like: This research was supported through the programme "Research in Pairs" (resp. "Oberwolfach Leibniz Fellows") by the Mathematisches Forschungsinstitut Oberwolfach in [year].

There are no requirements for the format of the preprint, except that the paper size (respectively format) should be DIN A4, "letter" or "article".

On the front page of the hard copies, which contains the logo of the MFO, title and authors, we shall add a running number (20XX - XX).

We cordially invite the researchers within the RiP or OWLF programme to make use of this offer and would like to thank you in advance for your cooperation.
