Exponential methods for anisotropic diffusion
Pranab J. Deka, Lukas Einkemmer, Ralf Kissmann
The anisotropic diffusion equation is imperative in understanding cosmic ray diffusion across the Galaxy, the heliosphere, and its interplay with the ambient magnetic field. This d…
A comparison of Leja- and Krylov-based iterative schemes for Exponential Integrators
Pranab J. Deka, Mayya Tokman, Lukas Einkemmer
Krylov-based algorithms have long been preferred to compute the matrix exponential and exponential-like functions appearing in exponential integrators. Of late, direct polynomial i…
LeXInt: Package for Exponential Integrators employing Leja interpolation
Pranab J. Deka, Lukas Einkemmer, Mayya Tokman
We present a publicly available software for exponential integrators that computes the functions using polynomial interpolation. The interpolation method at Leja points ha…
