  • Krilov solvability of unbounded inverse linear problems 
    Caruso, Noe; Michelangeli, Alessandro (SISSA, 2020-01-23)
    The abstract issue of ‘Krylov solvability’ is extensively discussed for the inverse problem Af = g where A is a (possibly unbounded) linear operator on an infinite-dimensional Hilbert space, and g is a datum in the range ...
  • Krylov Solvability of Unbounded Inverse Linear Problems 
    Caruso, Noè Angelo; Michelangeli, Alessandro (2019)
    . The abstract issue of ‘Krylov solvability’ is extensively discussed for the inverse problem Af = g where A is a (possibly unbounded) linear operator on an infinite-dimensional Hilbert space, and g is a datum in the range ...
  • On Krylov solutions to infinite-dimensional inverse linear problems 
    Caruso, Noe; Michelangeli, Alessandro; Novati, Paolo (SISSA, 2018-11)
    We discuss, in the context of inverse linear problems in Hilbert space, the notion of the associated infinite-dimensional Krylov subspace and we produce necessary and sufficient conditions for the Krylov-solvability of the ...
  • Truncation and convergence issues for bounded linear inverse problems in Hilbert space 
    Caruso, Noe; Michelangeli, Alessandro; Novati, Paolo (SISSA, 2018)
    We present a general discussion of the main features and issues that (bounded) inverse linear problems in Hilbert space exhibit when the dimension of the space is infinite. This includes the set-up of a consistent ...
