Bunse-Gerstner, Angelika; Guerra-Ones, Valia; La Vega, … - In: Mathematics and Computers in Simulation (MATCOM) 73 (2006) 1, pp. 65-75

We present a modified version of the two-level iterative method proposed in [M. Hanke, R. Vogel, Two-level preconditioners for regularized inverse problems. I: Theory, Numerische Mathematik 83 (1999) 385–402]. Here, we propose the application of the two-level Schur complement CG on the...
