Ill posed inverse problems

For a long time mathematicians felt that ill-posed problems cannot describe real phenomena and objects. However [...] the class of ill-posed problems includes many classical mathematical problems and, most significantly, that such problems have important applications.  Tikhonov

Inverse problems are concerned with determining causes for a desired or an observed effect or calibrating the parameters of a mathematical model to reproduce observations. Inverse problems most often do not fulfill Hadamard's postulates of well-posedness: they might not have a solution in the strict sense, solutions might not be unique and/or might not depend continuously on the data. Hence their mathematical analysis is subtle. However they have many applications in engineering, physics and other fields. Here are some web ressources on Ill posed inverse problems.
