Title:

A Library for Polynomial Computations - The Blossoming Classes

Abstract:

There are a lot of different schemes for curves and surfaces in CAGD. Almost all are based on piecewise polynomial functions. In spite of this similarity, the code to do the computations is different for each scheme.

For my thesis I'm writing a general-purpose library for doing piecewise polynomial computations. The difficulty lies in how to provide, in one library, for all the different computations required. The solution is to provide a small set of efficient high-level operations which can be used to code all needed computations easily.

In this talk, I will talk the library--the Blossom Classes--and the operations provided.

                Professor W. Gilbert


        " Newton's Method for Complex Roots "

                o------------------o

We first look at Newton's Method for approximating real roots
of functions, and consider a little of the history of the
method (Newton did one example and did not use calculus!).
We then apply the method to approximate complex roots.  When
does the method work and what can go wrong?  How can we modify
the method?  We show a connection with complex dynamics in
the plane and, of course, fractals.
