About

A mathematician specializing in nonlinear hyperbolic PDEs, geometric analysis of pseudo-Riemannian manifolds, and general relativity.

A few of my questions on MO have not yet received a complete answer. Some of them I think about in the course of my research. But this one is entirely orthogonal to my main research activity and I would love to know the answer!
