Abstract

This talk presents our recent progress in solving inverse boundary problems using only a single passive observation. The key to this result is a suite of new technical tools, chief among them a dimensional reduction technique (either parametric or geometric) and an operator-theoretic shift designed for nonlinear PDEs. These developments enable unique recovery of unknown parameters where previously multiple, active measurements were required.
