The mathematical works of Lars Ahlfors and Lipman Bers are
fundamental and lasting. They have influenced and altered the
development of twentieth century mathematics. The personalities of
these two scientists helped create a mathematical family and have had
a permanent positive effect on a whole generation of
mathematicians. Their mathematical heritage continues to lead
succeeding generations. In the fall of 1994, one year after Bers'
death, some members of this family decided to inaugurate a series of
conferences, The Bers Colloquium, to be held every three
years. The theme was to be a topic in the Ahlfors-Bers mathematical
tradition, broadly interpreted. Ahlfors died a year after the first
colloquium; future colloquia in this series will be called The
Ahlfors-Bers Colloquium.

The first colloquium was held in October 1995 at the Graduate
Center, CUNY in New York. It coincided roughly with the second
anniversary of Bers' death. There were six lectures and much informal
mathematical discussion. This volume contains papers by the speakers
and many of the participants. The broad range of papers indicates how
strong and far-reaching Bers' influence has been. The topics
represented in the book include Teichmüller theory, Kleinian
groups, higher dimensional hyperbolic geometry, geometry of numbers,
circle packings, theory of discrete groups, classical complex function
theory, one dimensional dynamics, fluid dynamics, quasiconformal
mappings in higher dimensions, partial differential equations, and
classical algebraic geometry.

Features:

- Twenty-seven very high-level papers on related topics
- Open problems
- Expository articles

#### Readership

Graduate students and research mathematicians interested in functions of a complex variable, and related areas of mathematics.
