noteLie derivatives on smooth manifolds are not currently formalized in Mathlib at this level of generality.Mathlib formalizes the Lie bracket of vector fields on manifolds (`VectorField.mlieBracket`, coinciding with the Lie derivative of a vector field along another), but the general Lie derivative acting on tensors/forms is not yet formalized.

noteThe Laplace transform and its inverse are not formalized in Mathlib.The Laplace transform and its inverse are not formalized in Mathlib (only Mellin and Fourier transforms are).

noteHankel functions are not formalized in Mathlib.Hankel functions (and Bessel functions more generally) are not formalized in Mathlib.
