Planned

  • Objective:

    During the current project of efficiently calculating a resynthesis window and an iterative scheme for a finite element method algorithm for vibrations in soils and liquids, it became apparent that block matrices are a powerful tool to find numerically efficient algorithms.

    Method:

    In this project, the focus should be the investigation of the numeric features of block matrices. How can this structure be used to calculate or approximate the inverse of a matrix or its norm? How can this be used to speed up iterative schemes?

    Application:

    The results will be used for the two projects mentioned below:

    • double preconditioning for Gabor frames
    • vibrations in random layers
