The solution set of a polynomial system decomposes into a union of
irreducible components. The set of polynomials imposes on each component a
positive integer known as the multiplicity of the component. This number is of
interest not only because of its meaning in applications but also because a
number of numerical methods have difficulty in problems where the multiplicity
of a component is greater than one. In this talk, I will discuss a numerical
algorithm for determining the multiplicity of a component of an algebraic set.
This is joint work with Chris Peterson and Andrew Sommese.
