Iterative methods for solving a nonlinear boundary inverse problem in glaciology
, 2009 We address a Cauchy problem for a nonlinear elliptic PDE arising in glaciology. After recasting the Cauchy problem as an ill-posed operator equation, we prove (for values of a certain parameter allowing Hilbert space techniques) differentiability ...

A quasi-boundary value method for regularizing nonlinear ill-posed problems
Electronic Journal of Differential Equations, 2009 In this article, a modified quasi-boudary regularization method for solving nonlinear backward heat equation is given. Sharp error estimates for the approximate solutions, and numerical examples to illustrate the effectiveness our method are provided.

, 2012 Via Carleman estimates we determine sufficient conditions ensuring uniqueness and continuous dependence results for a severely ill-posed linear integro-differential boundary-value parabolic problem with no initial condition.

Complexity of linear ill-posed problems in Hilbert space [PDF]
, 2016 Information complexity of ill-posed problems may be seen as controversial. On the one hand side there were pessimistic results stating that the complexity is innite, while on the other hand side the theory of ill-posed problems is well developed.

Ill-Posed Problems in Early Vision
, 1987 The first processing stage in computational vision, also called early vision, consists in decoding 2D images in terms of properties of 3D surfaces. Early vision includes problems such as the recovery of motion and optical flow, shape from shading ...

ILL-POSED PROBLEMS AND EXAMPLES OF INCORRECT PROBLEMS
This work examines the problem of ill-posed problems, which often arise in various fields of science and practice. Ill-posed problems are characterized by the lack of a unique solution, sensitivity to changes in input data, and instability of the ...
