Papers and Preprints

The pdf files for the preprints of  the new articles and of some of those already published can be downloaded by clicking on the title or on the number of the paper. Please note that the preprint may differ from the published article: existing laws forbid (I think) to modify preprints after the transfer of copyright. If you are interested in a reprint of  the article, please contact me here: languasco AT math.unipd.it (replace AT by @).
