Title:The Devil's Pentagram
Seminar:MASS Colloquium
Speaker:R. Schwartz, Brown University
Abstract:
The pentagram map is a simple iteration one performs on polygons. In the case of a regular pentagon, the diagram looks like the famous pentagram well-known to practitioners of black magic and other dark arts. In general, the construction gives rise to an interesting dynamical system that is related to determinants, integrable systems, and the monodromy of ordinary differential equations. I will explain the basic construction and give a partly visual tour of many features of the system.
