Colloquium: Apollonian Fractal — Numbers, Geometry, and Physics

Date: September 22, 2017
Time: 3:00 pm

Location: Planetary Hall Room 126

Featured Speaker:
Jerzy Kocik
Southern Illinois University, Department of Mathematics

Abstract:
Not only is the Apollonian configuration of circles an aesthetically noteworthy fractal but it also possesses a surprisingly rich mathematical structure. In particular, it conceals the main ingredients of modern physics, like Minkowski space-time, a model of spin, analogies of the quantum Aharonov-Bohm-like phenomena, and more. We shall gently explore these results, uncovering facts that should be found interesting and inspiring to students, researchers, and enthusiasts of geometry and physics.

Refreshments will be served.

Colloquium: Mathematics and Climate

Date: September 8, 2017
Time: 3:00 pm

Location: Planetary Hall Room 126

Featured Speaker:
Hans G. Kaper
Georgetown University and Mathematics and Climate Research Network

Abstract:
Mathematical models and statistical arguments play a central role in the assessment of the changes that are observed in Earth’s climate system. While much of the discussion of climate change is focused on large-scale computational models, the theory of dynamical systems provides the language to distinguish natural variability from change. In this talk I will discuss some problems of current interest in climate science and indicate how, as mathematicians, we can find inspiration for new applications.
