I work with Mathematica and other software to model objects in low dimensional, geometric topology. I am particularly interested in modeling perspectively correct views of the interior of homogeneous manifolds, the developing maps of projective structures on surfaces, and animations for teaching mathematics courses.

Radius of Convergence

Video

2018

This is a video of successive approximations of the rational function z/(z+1) by truncated Taylor series, as the base point moves about the plane. This video was produced to accompany a complex analysis course, and show visually the connection between the basepoint, radius of convergence, and location of singularities.
