Understanding the dynamical evolution of dense stellar systems,                 such as globular clusters and galactic nuclei, is one of the most               fundamental problems of gravitational astrophysics.  Substantial                progress towards this goal has been made in recent years as a                   result of both theoretical and observational advances.  Frequent                star-star gravitational interactions cause a profound evolution                 of the overall structure of these systems on astrophysically                    interesting time scales.  Powerful computer simulation methods                  have firmly established the inevitable evolution of globular                    clusters of stars toward the collapse of the core of the cluster.               The advent of new observing instrumentation and the ability to                  achieve high angular resolution from ground based observatories                 have both led to significant advances in the observational study                of globular clusters and galactic nuclei.                                                                                                                       Drs. Cohn, Lugger, and Durisen, at the University of Indiana,                   have undertaken a major research effort to extend our                           understanding of stellar cluster evolution.  Supercomputers have                become an essential tool in this investigation.  Globular                       clusters provide an excellent laboratory for observational tests                of the stellar dynamical theory that underlies this group's                     models of normal and active galactic nuclei.  The wealth of                     observational data on the structure of globular clusters and                    galactic nuclei that is being acquired by this group and others                 provides a firm basis for the theoretical modeling.
