Proofs To Go

At the age of eleven, I began Euclid, with my brother as my tutor.
This was one of the great events of my life, as dazzling as first love.
I had not imagined there was anything so delicious in the world.

Recent Research and Projects
C.K. Han, J.W. Oh, and I generalized the notion of a Jacobi field along a geodesic to that of an infinitesimal isometry along an arbitrary C2 curve in a Riemannian manifold. I recenlty visited Han at the Korea Institute for Advanced Study, where we worked on a generalization of the Frobenius foliation theorem.  I also visited Sergei Tabachnikov and Mark Levi at Penn State, where we worked on bicycle tire track geometry. In a recent paper I explored the connection between the volume swept out by a moving planar region and the motion of its centroid. I am working on an extension of this to spherical and hyperbolic geometry. Patrick Coulton, Gregory Galperin, and I studied pendulum dynamics in spherical and hyperbolic geometries. Ralph Alexander, David Berg, and I worked out new formulas for perimeters of convex regions in spherical and hyperbolic geometries. I continue to be interested in the geometry of planimeters, and the connections between planimeters and isoperimetric inequalities.
