Spectral analysis and sine transform based preconditioning for a structure preserving stabilized scheme approximating the space-fractional Allen Cahn equation with logarithmic potential

Danyal Ahmad, Stefano Serra-Capizzano, Muhammad Sohaib +1

We consider an initial boundary value problem of the space fractional Allen-Cahn equation with logarithmic Flory-Huggins potential. As an approximation technique, first-order weigh…

Structure-preserving preconditioning of discrete space-fractional diffusion equations with variable coefficient and θ-Method

Muhammad Faisal Khan, Asim Ilyas, Rolf Krause +2

This paper studies the spectral properties of large matrices and the preconditioning of linear systems, arising from the finite difference discretization of a time-dependent space-…
