Krylov subspace residual and restarting for certain second order differential equations

M. A. Botchev, L. A. Knizhnerman, M. Schweitzer

We propose algorithms for efficient time integration of large systems of oscillatory second order ordinary differential equations (ODEs) whose solution can be expressed in terms of…

Model order reduction of layered waveguides via rational Krylov fitting

Vladimir Druskin, Stefan Güttel, Leonid Knizhnerman

Rational approximation recently emerged as an efficient numerical tool for the solution of exterior wave propagation problems. Currently, this technique is limited to wave media wh…
