Complex Analysis Seminar

The Complex Analysis Seminar is centered on complex analysis and its interactions with other areas of mathematics. Its principal interests include analysis on metric measure spaces, geometric function theory and complex dynamics. Geometric connections encompass Riemann surfaces, Kleinian groups, hyperbolic geometry, Teichmüller theory, and geometric group theory. At the interface with probabili...

Geometry and Topology Colloquium

Title: The StingrayAbstract: The Earle slice S is an open domain in a 1-dimensional (complex) curve of the SL(2,C) character variety of a rank 2 free group, which is a model for the Teichmuller space of a once-punctured torus. It bears a remarkable resemblance to J, the Julia set of z -> z^2 + 1/4. Connected quadratic Julia sets are parameterized by the Mandelbrot set. This raises the question:...
