Conforming and nonconforming finite element methods for biharmonic inverse source problem [PDF]

open access: yesInverse Problems, 2021
Abstract This paper deals with the numerical approximation of the biharmonic inverse source problem in an abstract setting in which the measurement data is finite-dimensional. This unified framework in particular covers the conforming and nonconforming finite element methods (FEMs).
