Abstract : This workshop covered various techniques in nuclear many-body problems as well as various theoretical techniques, ranging through the coupled cluster method, variational Jastrow-like approaches, parquet theory etc. Particular emphasis was placed on the technique of density functional theory (plus a little on density matrices), a wide range of applications including atomic cluster theory, inhomogeneous liquids and especially He(4), simple metals and metal surfaces. In this context, there was a special session, with two papers related to the density-functional technique; one on time-dependent theory and the other on the many-body construction of density functionals with illustrative applications. Other especially notable contributions applied information turning from (mainly) techniques to physical areas in condensed matter, there was considerable emphasis on the quantal liquid He(4), with discussion not only of bulk properties but of wetting, surface tension and H(3) and He(4) mixtures. Contact with new neutron scattering experiments was highlighted in connection with bulk He(4). Some papers on high Tc materials, plus a discussion of recent progress, both experiment and theory, on electron solids, reflected important growth areas in condensed matter. In the latter area, the equilibrium between Laughlin electron liquid and electron solid was considered, the electron liquid being treated in a number of papers, including a study by quantal hypernetted chain methods.
