The Journal of Operator Theory is published by the Theta Foundation in Bucharest with the cooperation of the Institute of Mathematics "Simion Stoilow" of the Romanian Academy. The Journal of Operator Theory endeavours to publish significant articles in all areas of operator theory, operator algebras and closely related domains. Two volumes are published each year and each volume consists of two issues.Manuscripts can be written in English (preferable), French, or German. Preference will be given to manuscripts between 10 and 40 typewritten pages. High standards are applied in evaluating submitted papers. To submit a paper, an author should either mail two hard paper copies of the manuscript or e-mail the manuscript as a PDF file, to one of the Editors. In both cases, a submission cover letter is needed. The submission of a paper carries with it the author's assurance that it has not been copyrighted, published, or submitted for publication elsewhere. Detailed instructions for authors can be seen in the Guidelines for Authors. After acceptance, authors should e-mail the source file (AMS-LaTeX, LaTeX, AMS-TeX, TeX, or the like) to the Editorial Office in Bucharest.
