Criticism of "Necessity of simultaneous co-existence of instantaneous
and retarded interactions in classical electrodynamics" by Andrew E.
Chubykalo and Stoyan J. Vlaev
The demonstration that the electromagnetic fields derived from the
Lienard-Wiechert potentials do not satisfy the Maxwell equations is proved to
be false. Errors were made in the computation of the derivatives of retarded
quantities. The subsequent inference of the necessity of both instantaneous and
retarded electromagnetic interactions cannot be made. Different choices of
gauge can lead to a variety of forms for the scalar and vector potentials,
always with the same retarded fields. Classical electromagnetic theory is
complete as usually expressed. One may choose to work in the Lorenz gauge in
which all quantities are retarded.Comment: pdf file, 5 pages, submitted to Int. J. Mod. Phy
