** Editorial policy**
The journal *Rendiconti dell’Istituto di Matematica dell’università di Trieste * publishes original articles in all areas of mathematics. Special regard is given to research papers, but attractive expository papers may also be considered for publication.
The journal usually appears in one issue per year. Additional issues may however be published. In particular, the Managing Editors may consider the publication of supplementary volumes related to some special events, like conferences, workshops, and advanced schools.
All submitted papers will be refereed. Manuscripts are accepted for review with the understanding that the work has not been published before and is not under consideration for publication elsewhere.
Our journal can be obtained by exchange agreements with other similar journals.

**Instructions for Authors**
Authors are invited to submit their papers by e-mail directly to one of the Managing Editors in PDF format.
All the correspondence regarding the submission and the editorial process of the paper are done by e-mail.

Abstracts should not exceed ten printed lines, except for papers written in French, German, or Italian,
for which an extended English summary is required.
After acceptance, manuscripts have to be prepared in LaTeX using the style rendiconti.cls which can be downloaded from the web page.
Any figure should be recorded in a single PDF, PS (PostScript), or EPS (Encapsulated PostScript) file.
