| Abstract: |
| Nonlinear ultrasound waves are widely used in medical imaging. The propagation of high-intensity ultrasound waves can be modeled by nonlinear wave equations. In this talk, we consider an inverse problem for a nonlinear wave equation with a general nonlinearity. We show the Dirichlet-to-Neumann map (DN map) determines the nonlinearity. We also consider inverse problems for nonlinear wave equations with a general nonlinear term and a damping term. |
