Regularization of linear ill-posed problems involving multiplication operators
Peter Mathé, M. Thamban Nair, Bernd Hofmann
We study regularization of ill-posed equations involving multiplication operators when the multiplier function is positive almost everywhere and zero is an accumulation point of th…

On truncated spectral regularization for an ill-posed evolution equation
M. Thamban Nair
In this note we consider the {\it spectral truncation} as the regularization for an ill-posed non-homogeneous parabolic final value problem, and obtain error estimates under a genr…
