内容简介:The stochastic inverse problem originates from practical problems such as resource exploration, medical imaging, and stealth technology. It uses stochastic differential equations as a mathematical model to describe the inverse problem under the perturbation of random noises such as environmental changes and measurement errors. It aims to study the uniqueness, stability and other theories of stochastic inverse problems based on external observable random information, and construct efficient numerical calculation methods to reveal the distribution structure and statistical information of unobservable random parameters within the system. This talk will focus on time-harmonic wave equations, and give a brief introduction on the uniqueness, stability, and numerics of corresponding stochastic inverse problems.
