A Unified Rational Krylov Method for Elliptic and Parabolic Fractional Diffusion Problems

Tobias Danczul, Clemens Hofreither, Joachim Schöberl

We present a unified framework to efficiently approximate solutions to fractional diffusion problems of stationary and parabolic type. After discretization, we can take the point o…

On Rational Krylov and Reduced Basis Methods for Fractional Diffusion

Tobias Danczul, Clemens Hofreither

We establish an equivalence between two classes of methods for solving fractional diffusion problems, namely, Reduced Basis Methods (RBM) and Rational Krylov Methods (RKM). In part…

A Reduced Basis Method For Fractional Diffusion Operators II

Tobias Danczul, Joachim Schöberl

We present a novel numerical scheme to approximate the solution map s↦u(s):=L−sf to partial differential equations involving fractional elliptic operators.…

A Reduced Basis Method For Fractional Diffusion Operators I

Tobias Danczul, Joachim Schöberl

We propose and analyze new numerical methods to evaluate fractional norms and apply fractional powers of elliptic operators. By means of a reduced basis method, we project to a sma…
