The Cortona Conference is a biennial meeting of all Italian groups from about 20 universities who are active in theoretical nuclear physics. This volume presents the main achievements and perspectives of Italian theoretical nuclear physics, with particular reference to the last two years. The first part contains the invited talks on: nuclear structure; light nuclei physics; hadronic degrees of freedom; nuclear physics with electroweak probes; nuclear dynamics and nuclear matter; and first results about the AIACE experiment. Furthermore it includes two longer communications on: nuclear physics...
