Approximation of Periodic PDE Solutions with Anisotropic Translation Invariant Spaces

Numerical Analysis 2018-12-10 v1

Abstract

We approximate the quasi-static equation of linear elasticity in translation invariant spaces on the torus. This unifies different FFT-based discretisation methods into a common framework and extends them to anisotropic lattices. We analyse the connection between the discrete solution spaces and demonstrate the numerical benefits. Finite element methods arise as a special case of periodised Box spline translates.
