GFM notes

Those are quick numerical investigations on a particular aspect of iterative PinT methods using the GFM library. Each note correspond to a Jupyter notebook that details the whole experiment.

1. A quick comparison of "volume" and "interface" solvers
2. Numerical investigation of the nullity of the Δ𝜒 operator
3. Investigating the elemental two-level time multigrid methods
4. Two approaches for defining a collocation method
