Minimal example of finite element method for the spectral fractional Laplacian in FEniCSx

A minimal example of adaptive finite element method for the two-dimensional spectral fractional Laplacian based on the FEniCSx library FEniCS-Error-Estimation (FEniCS-EE) is provided.

FEniCS-EE is an open source library showing how hierarchical estimators of Bank-Weiser type can be implemented using the FEniCS Project finite element solvers DOLFIN and DOLFINx (https://fenicsproject.org).

The code and Docker images archived here was submitted with the pre-print of the paper.
