Title: Inverse problems with passive measurements and applications

Abstract: We are concerned with a class of inverse problems where one intends to recover certain unknown sources and/or mediums by using passive measurements. This type of inverse problems arises in a variety of cutting-edge applications including geometric body generation, photo-acoustic tomography, MAD (magnetic anomaly detection) technology, earthquake precursor detection and cosmological exploration. In this talk, I shall discuss the mathematical progress of our study including the modeling, unique identifiability, stability, and numerical reconstruction results, as well as applications.
