... How does f(x0) relate to averages of f(x) at nearby positions? Therefore fε(0) = f(0) + (ε/d) ∇2 f(0) + … The Laplacian provides a measure of how the spherical average of a function changes as the radius increases. Quantum mechanics is a mystery, but in so far as a classical interaction V(x) at a ...
