This volume contains the proceedings of three
AMS Special Sessions on Computational Algebraic and Analytic Geometry
for Low-Dimensional Varieties held January 8, 2007, in New Orleans,
LA; January 6, 2009, in Washington, DC; and January 6, 2011, in New
Orleans, LA.

Algebraic, analytic, and geometric methods are used to study
algebraic curves and Riemann surfaces from a variety of points of
view. The object of the study is the same. The methods are
different. The fact that a multitude of methods, stemming from very
different mathematical cultures, can be used to study the same objects
makes this area both fascinating and challenging.

#### Readership

Graduate students and research mathematicians interested in computational aspects of algebraic and analytic geometry.
