# Topics in Algebraic Geometry and Geometric Modeling

Algebraic geometry and geometric modeling both deal with curves and
surfaces generated by polynomial equations. Algebraic geometry investigates the
theoretical properties of polynomial curves and surfaces; geometric modeling
uses polynomial, piecewise polynomial, and rational curves and surfaces to
build computer models of mechanical components and assemblies for industrial
design and manufacture.

The NSF sponsored the four-day “Vilnius Workshop on Algebraic Geometry
and Geometric Modeling”, which brought together some of the top experts
in the two research communities to examine a wide range of topics of interest
to both fields. This volume is an outgrowth of that workshop. Included are
surveys, tutorials, and research papers. In addition, the editors have included
a translation of Minding's 1841 paper, “On the determination of the
degree of an equation obtained by elimination”, which foreshadows the
modern application of mixed volumes in algebraic geometry.

The volume is suitable for mathematicians, computer scientists, and
engineers interested in applications of algebraic geometry to geometric
modeling.
