  • Speaker: ZOU Jun (The Chinese University of Hong Kong)

  • Time: Mar 15, 2019, 16:10-17:10

  • Location: Conference Room 415, Hui Yuan 3#

ABSTRACT:

In this talk we shall review the background and applications of general inverse problems and some recent mathematical and numerical developments in direct sampling methods for both nonlinear wave-type and non-wave-type inverse problems. Some general motivations, principles and justifications are discussed for the choices of several key ingredients of the direct sampling methods in an optimization framework, and numerical experiments are presented for various inverse problems.
