Boston University

Kieval Lecture

Spring, 1998

Chaos Games and Fractal Geometry

April 23, 1998 @ 8:00 P.M.
NR 101
Using a variety of  chaos games, the Kieval Lecture will explore how fractal images are
created, manipulated, and made into animations.  We'll challenge the audience to "Beat the Professor" in a chaos game or two.  And we'll discuss applications ranging from fractal moviemaking in Hollywood to data compression.

Mathematics Department Colloquium

  Colloquium:  The Mandelbrot Set, the Farey tree, and the Fibonacci Sequence

April 23, 1998 @ 4:00 p.m. NR 101
Tea @ 3:30 p.m. - outside Library 56

Abstract: In this talk we discuss the arithmetic and geometry of the bulbs in the Mandelbrot set.  We first show the visual relationship between these bulbs and the Farey tree.  Then we discuss how to make these results rigorous using the external rays of Douady and Hubbard.
