Colloquium

• Michael Bolt, Calvin College, Paint by number: a visualization of complex functions.
  • One challenge to understanding complex analysis is the difficulty one can have in forming an intuition for analytic functions. Frank Farris found a new way to visualize complex functions. The idea is to associate numbers with colors and to paint a domain with the values of the associated function. In this talk we describe different implementations of domain coloring and contrast it with the usual transformational approach. We also use domain coloring to illustrate some of the nice theorems in complex analysis.

• Student Talks: L. Hicks, R. Lucas, N. Pham, D. Swartz.
• Prof. Michael Bolt, Calvin College, The mathematics of Escher's "Print Gallery".
  • One of Escher's more compelling works is "Print Gallery" in which a young man stands in an art gallery, viewing a print that contains the very gallery in which he is standing. At the center is a curious hole, blank except for the artist's signature. In 2000, Hendrik Lenstra discovered the mathematical structure behind "Print Gallery" and showed there is a unique solution for what belongs in the hole. In this talk, we'll see how a team of scientists filled in the hole and generated a number of images and animations that illustrate other versions of the picture. Along the way, we'll introduce all the complex analysis that is needed to generate images like Escher's. The mathematics should be understandable to anyone with a year of calculus.
