Abstract:  

The inverse problem we address in this talk is whether we can determine the structure of a region in space-time by measuring point light sources coming from the region. We can also observe gravitational waves since the LIGO detection in 2015. We will also consider inverse problems for nonlinear hyperbolic equations, including Einstein's equations and an equation arising in nonlinear acoustics, involving active measurements.
