The representations of a finitely generated group in a topological group \(G\) form a topological space which is an analytic variety if \(G\) is a Lie group, or an algebraic variety if \(G\) is an algebraic group. The study of this area draws from and contributes to a wide range of mathematical subjects: algebra, analysis, topology, differential geometry, representation theory, and even mathematical physics. In some cases, the space of representations is the object of the study, in others it is a tool in a program of investigation, and, in many cases, it is both.

Most of the papers in this volume are based on talks delivered at the
AMS-IMS-SIAM Summer Research Conference on the Geometry of Group
Representations, held at the University of Colorado in Boulder in July 1987.
The conference was designed to bring together researchers from the diverse
areas of mathematics involving spaces of group representations. In keeping
with the spirit of the conference, the papers are directed at nonspecialists,
but contain technical developments to bring the subject to the current research
frontier. Some of the papers include entirely new results. Readers will gain
an understanding of the present state of research in the geometry of group
representations and their applications.
