Regularization of Inverse Ill-Posed Problems with General Penalizing Terms: Applications to Image Restoration
(Asociación Argentina de Mecánica Computacional, 2010-11)
The Tikhonov-Phillips method is widely used for regularizing ill-posed problems due to the simplicity of its formulation as an optimization problem. The use of different penalizers in the functionals associated to the ...

Generalized qualification and qualification levels for spectral regularization methods
(Springer/Plenum Publishers, 2009-06)
The concept of qualification for spectral regularization methods (SRM) for inverse ill-posed problems is strongly associated to the optimal order of convergence of the regularization error (Engl et al. in Regularization ...

H2 regularity for the p(x)-Laplacian in two-dimensional convex domains
(Academic Press Inc Elsevier Science, 2014-02)
In this paper we study the H2 global regularity for solutions of the p(x)-Laplacian in two-dimensional convex domains with Dirichlet boundary conditions. Here p:Ω→[p1, ∞) with p∈Lip(Ω-) and p1>1.
Total least squares problems on infinite dimensional spaces
(IOP Publishing, 2021-04)
We study weighted total least squares problems on infinite dimensional spaces. We present some necessary and sufficient conditions for the regularized problem to have a solution. The existence of solution can also be assured ...
