## Survey Articles on Geometric Models for Noncommutative Algebras

The papers in this volume were written by graduate students in the
course Math 277, Topics in Differential Geometry, in the Spring
Semester of 1997. The papers were revised by the authors after a
reading by one other student and the instructor.
We hope that these papers will
be useful for students and researchers interested in a quick look at
several aspects of symplectic and Poisson geometry and their relations
to the theory of operator algebras.
