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: (1) Nuclear structure, (2) Light nuclei physics, (3) Hadronic degrees of freedom, (4) Nuclear physics with electroweak probes, (5) Nuclear dynamics and nuclear matter, and (6) First results about the AIACE experiment. Furthermore it includes two longer communications on: (7) Nuclear physics with exotic beams, and (8) Solution of the folding problem in protein models. The second part contains contributed papers.Contents:Contributed Papers:Nuclear Structure and Related AreasFew-Nucleon SystemsHadronic Degrees of FreedomNuclear Physics with Electroweak ProbesNuclear Matter and Nuclear DynamicsReadership: Graduate students and researchers in theoretical nuclear physics and related areas.Key Features:The first systematic treatment of exploring the structure of associative algebras in terms of Gröbner bases, including up-to-date researchA useful and practical reference on (noncommutative) Gröbner basesSuitable for use in an advanced lecture course on computational (noncommutative) algebra
