Title：

Stochastic inverse problems for both time-harmonic and time-dependent wave equations

Abstract:

The stochastic inverse problem originates from practical issues such as resource exploration, medical imaging, and stealth technology, using stochastic differential equations as mathematical models to describe the problem under the interference of random factors such as environmental uncertainties and data noise. This talk will introduce the uniqueness, stability, and computational methods of inverse problems for random sources and random potentials in the context of both time-harmonic and time-dependent wave equations.
