Abstract
[en] This study focuses on Krylov iterative solvers and introduces subspace recycling methods to reuse information in various resolutions needed for full waveform inversion.
The efficiency of these methods is assessed across different numerical applications.
Additionally, partial subspace recycling is presented along with proposed selection strategies that are briefly analyzed.
