Comparative Analysis of Different Preconditioning Methods in Electromagnetic Scattering Problems using MoM-FMM
- Computer ScienceIEEE Latin America Transactions
- 2021
In this work, some preconditioning techniques are revised and applied to a linear equation system derived from such type of problems, and the performance of these preconditionsers is estimated and analyzed comparatively using the generalized minimal residual iterative method.

Adaptive Krylov-Type Time Integration Methods
- Computer ScienceArXiv
- 2019
Two approaches for improving the stability and efficiency of Rosenbrock-Krylov methods are proposed, one through direct control of linear system residuals and the second through a novel extension of the underlying Krylov space to include stage right hand side vectors.
