Before revision:  Upon discretization, the model inherits several desirable attributes from this infinite-dimensional , function space viewpoint, including mesh-invariant approximation error with respect to the true PDE solution map and the capability to be trained at one mesh resolution and then deployed at different mesh resolutions.
