On incorrectness of application of the Helmholtz decomposition to microscopic electrodynamics
Abstract
The integral expressions served to decompose vector field into irrotational and divergence-free components represent modern version of the Helmholtz decomposition theorem. These expressions are also widely used to decompose the electromagnetic fields. However, an appropriate analysis of application of these expressions to electrodynamics shows that the improper integral arising in the procedure for calculating these components makes such a decomposition impossible.
