Using the Lagrange-Gordeyev method for retarded fields, a technique is deve
loped in order to find an equation of motion for a point charged particle f
or each different physical assumption. As is expected, for a point charged
particle, Lorentz-Dirac equation is obtained without using advanced fields.
Rohrlich-Boyer controversy is avoided in this process since only fluxes of
energy are considered. An amazing renormalization appears when Abraham-Bec
ker proposal is calculated.
