1991 annual report to the National Science Foundation

The Geometry Center research program has a number of different aspects, most of which involve longer term commitments, such as, development of research software, teams of individuals visually exploring mathematical structures and sponsoring of workshops. The Center is built on the research programs of its faculty. These programs have flourished and interacted under the Center umbrella. There are many interconnections and commonalities between the fields represented. Here, a summary of the research work of each of the faculty members. Some of the research topics are geometric calculus of variations, group theory, geometric algorithms, and computer graphics
