Newton's method, zeroes of vector fields, and the Riemannian center of mass
David Groisser
We present an iterative technique for finding zeroes of vector fields on Riemannian manifolds. As a special case we obtain a ``nonlinear averaging algorithm'' that computes the cen…

Simple Type and the Boundary of Moduli Space
David Groisser, Lorenzo Sadun
We measure, in two distinct ways, the extent to which the boundary region of moduli space contributes to the ``simple type'' condition of Donaldson theory. Using a geometric repres…
