The measured data in thermoacoustic tomography with ideal point
detectors is the trace on (part of) the boundary of a domain of the
solution of an initial value problem for the wave equation. In this
talk I will present a range characterization for the traces of
solutions of the constant speed wave equation with one non-zero smooth
initial datum in the ball in odd dimensions. (This is joint work with
Rakesh.) I will also discuss inversion in one model where detectors
have anisotropic response.
